Thai Payroll Service — Payslips, PND.1, SSO Compliance — overview and who it is for

Notably, "Thai Payroll Service — Payslips, PND.1, SSO Compliance" sits inside our Tax, Accounting & Audit practice. The live path starts at "Register with SSO" and closes at "Year-end reports", typically Monthly end to end, with service pricing from ฿3,500–20,000/month — itemised up front so you can see what is our fee and what is a government charge.

Cross-service questions, answered by the NYC Legal team

363. Within how many days must a company update a work permit if the foreign employee changes job titles or office locations?

Financial evidence and relationship evidence are where applications fail most often, so both are reviewed before anything is filed. Processing time depends on each authority's queue, so the working order and the expected return date are confirmed before any work begins. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list. The workable order is: check that the source document is complete and legible, translate it, certify the translation, file for legalisation with the Department of Consular Affairs, then obtain the destination embassy's certification — or an Apostille where the destination is a convention party. Caution: each certification covers only what its own stamp states; it does not make a document automatically acceptable everywhere. Confirm the receiving authority's conditions case by case. Keep a digital copy of the finished certified set so it can be referenced if the destination asks for additional documents or a re-filing. Caution: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed. Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.

416. Can a lawyer file a court petition to appoint an estate administrator for foreign heirs not residing in Thailand?

Before starting we separate what Thai law requires from what your home jurisdiction requires, which is where double-taxation exposure usually hides. Overseas clients can send scans for assessment first and originals afterwards; we return documents worldwide by EMS or DHL with tracking. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list. Private documents such as powers of attorney or contracts must first pass a notarial services attorney before they can enter the legalisation stage. Caution: never unbind, trim or separate pages after an authority has sealed the set — doing so voids the certification. Send scans of every page for review before sending originals; that is when faded seals, passport-spelling mismatches and expired documents can still be corrected. Caution: government fees follow the authority's published rate and are separate from professional fees; check the current rate on the official website first. Request more than one certified set when several authorities are involved, because most receiving offices keep the certified copy and do not return it. Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.

Which office must be approached first for preparing Thai tax and legal documents for overseas filing, and with which documents?

Accounting, tax, property and estate work for foreign nationals is run jointly with our auditors and lawyers so the translated file and the filed file always match. Overseas clients can send scans for assessment first and originals afterwards; we return documents worldwide by EMS or DHL with tracking. Tell us where the document will be used and you will get a plan and a price the same business day. Fix three facts before any work starts: the destination country, the exact authority the file goes to, and the language that authority requires. Those three decide the whole certification chain. Caution: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed.

439. Does your criminal defense law firm represent foreign victims of fraud or scams in Thailand?

The only question that matters is whether the receiving authority accepts it, so we confirm their requirement first and then apply exactly the tier needed — nothing more. Quotations separate government fees from professional fees line by line, so nothing appears on the invoice that was not in the quote. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list. Request more than one certified set when several authorities are involved, because most receiving offices keep the certified copy and do not return it.

561. How does a foreign-owned restaurant secure a direct sales and direct marketing business license?

For import, export and special licences we keep the Board of Trade and agency template packs ready in advance. Processing time depends on each authority's queue, so the working order and the expected return date are confirmed before any work begins.

1,600 questions on accounting, tax, payroll and audit — answered by NYC Legal

Q78052.What should a first-time filer check in withholding tax and the 50 Tavi certificate before pressing submit?

The payer must withhold tax according to the type of income, issue the withholding certificate (form 50 Tavi) to the payee and remit it on PND.3 (individual payees) or PND.53 (juristic payees) by the 7th of the following month, with an extension when filing electronically. Build a monthly and annual tax calendar for the business and name an owner for each return so no deadline is missed and no surcharge accrues. Watch out: withholding at the wrong rate or remitting late triggers the 1.5% monthly surcharge and an amended return. Verify current rules and forms with the Revenue Department (rd.go.th), the DBD (dbd.go.th), the Social Security Office (sso.go.th), the Federation of Accounting Professions (tfac.or.th) and the Department of Consular Affairs (consular.mfa.go.th). Professional fees are quoted per case based on document volume and scope — ask our team by phone, LINE or email. VAT-registered operators file form P.P.30 monthly and maintain input/output tax reports that agree with the tax invoices issued and received in that month. Verify forms and deadlines with the Revenue Department (rd.go.th) and financial-statement requirements with the Department of Business Development (dbd.go.th).

Q75778.At which point in the filing calendar, surcharges and penalties is journals and general ledgers needed, and who issues it?

Late filing or underpayment attracts a surcharge of 1.5% per month of the tax due under the Revenue Code, plus penalties depending on the return type, while failure to submit financial statements to the DBD carries fines under the Accounting Act. Keep each document paired with its ledger entry and check that the tax ID and registered name match on every page. Watch out: failing to hold the AGM on time or to submit financial statements carries fines for both the company and its directors. Verify current rules and forms with the Revenue Department (rd.go.th), the DBD (dbd.go.th), the Social Security Office (sso.go.th), the Federation of Accounting Professions (tfac.or.th) and the Department of Consular Affairs (consular.mfa.go.th). Professional fees are quoted per case based on document volume and scope — ask our team by phone, LINE or email. Foreign nationals earning income in Thailand should first establish their tax-residency status by counting days of presence in the tax year, because that status determines which income must be brought into the calculation. Verify forms and deadlines with the Revenue Department (rd.go.th) and financial-statement requirements with the Department of Business Development (dbd.go.th).

Q75766.At which point in the filing calendar, surcharges and penalties is the withholding tax certificate (form 50 Tavi) needed, and who issues it?

Professional fees are quoted per case based on document volume and scope — ask our team by phone, LINE or email. In practice, assemble the source documents first — input and output tax invoices, receipts, bank statements and related contracts — then post them by period so the ledger reconciles with the return you are about to file. Verify forms and deadlines with the Revenue Department (rd.go.th) and financial-statement requirements with the Department of Business Development (dbd.go.th).

Q333064.What name-spelling and date pitfalls should be watched in using e-Tax Invoice and electronic documents?

The Revenue Department accepts returns and payments through e-Filing and supports e-Tax Invoice and e-Receipt for approved operators, which requires a digital certificate and data retention under the criteria the department publishes. Build a monthly and annual tax calendar for the business and name an owner for each return so no deadline is missed and no surcharge accrues. Watch out: a tax invoice missing any particular required by the Revenue Code can cost you the input VAT credit. Verify current rules and forms with the Revenue Department (rd.go.th), the DBD (dbd.go.th), the Social Security Office (sso.go.th), the Federation of Accounting Professions (tfac.or.th) and the Department of Consular Affairs (consular.mfa.go.th).

Q75586.How should an import-export business set up its process for transfer pricing and the disclosure form so nothing has to be redone later?

Sections 71 bis and 71 ter of the Revenue Code require related companies with revenue of THB 200 million or more in an accounting period to file the transfer pricing disclosure form together with PND.50 and to have a local file ready when the tax officer requests it. Keep each document paired with its ledger entry and check that the tax ID and registered name match on every page. Watch out: failing to hold the AGM on time or to submit financial statements carries fines for both the company and its directors. Verify current rules and forms with the Revenue Department (rd.go.th), the DBD (dbd.go.th), the Social Security Office (sso.go.th), the Federation of Accounting Professions (tfac.or.th) and the Department of Consular Affairs (consular.mfa.go.th).

Verify forms and deadlines with the Revenue Department (rd.go.th) and financial-statement requirements with the Department of Business Development (dbd.go.th).

Q75912.How does accounting and tax documents for overseas or bank use differ between a newly trading business and an established one?

Accounting and tax documents — audited financial statements, tax payment receipts or a certificate of tax residence (R.O.22) — must be translated, have the translation certified and be legalised at the Department of Consular Affairs before any destination-embassy step, as required by the receiving party. If a loan, licence renewal or visa application depends on the figures, allow lead time to close the books and obtain certified copies. Watch out: expenses without documentation identifying the recipient are commonly added back as non-deductible for corporate income tax. Verify current rules and forms with the Revenue Department (rd.go.th), the DBD (dbd.go.th), the Social Security Office (sso.go.th), the Federation of Accounting Professions (tfac.or.th) and the Department of Consular Affairs (consular.mfa.go.th).

Q333040.How does personal income tax filing for foreigners in Thailand differ when handled through an agent, and which suits whom?

Personal income tax is filed on PND.90 or PND.91 by 31 March of the following year — online filing receives an extension announced by the Revenue Department — and certain income types also require the half-year PND.94 return. If a loan, licence renewal or visa application depends on the figures, allow lead time to close the books and obtain certified copies. Watch out: expenses without documentation identifying the recipient are commonly added back as non-deductible for corporate income tax. Verify current rules and forms with the Revenue Department (rd.go.th), the DBD (dbd.go.th), the Social Security Office (sso.go.th), the Federation of Accounting Professions (tfac.or.th) and the Department of Consular Affairs (consular.mfa.go.th).

Q75324.At which point in monthly bookkeeping and accounting-record retention is a full-form tax invoice needed, and who issues it?

The Accounting Act B.E. 2543 (2000) requires the person with the duty to keep accounts to appoint a qualified bookkeeper, record transactions under the applicable financial reporting standards and retain the accounts and supporting documents for at least five years. A practical order is: confirm the accounting period and which taxes apply, collect source documents (tax invoices, receipts, payslips), reconcile against bank records, then file and keep the filing evidence. Watch out: a tax invoice missing any particular required by the Revenue Code can cost you the input VAT credit. Verify current rules and forms with the Revenue Department (rd.go.th), the DBD (dbd.go.th), the Social Security Office (sso.go.th), the Federation of Accounting Professions (tfac.or.th) and the Department of Consular Affairs (consular.mfa.go.th).

Q233058.What is the most common mistake in bookkeeping and retaining supporting documents, and how is it prevented in advance?

The Accounting Act B.E. 2543 (2000) requires the person with the duty to keep accounts to appoint a qualified bookkeeper, record transactions under the applicable financial reporting standards and retain the accounts and supporting documents for at least five years. If a loan, licence renewal or visa application depends on the figures, allow lead time to close the books and obtain certified copies. Watch out: withholding at the wrong rate or remitting late triggers the 1.5% monthly surcharge and an amended return.

Q75514.How should a factory with a large payroll set up its process for the CPA audit and filing of financial statements so nothing has to be redone later?

A limited company's financial statements must be audited and opined on by a CPA registered with the Federation of Accounting Professions, approved at an annual general meeting held within four months of the year end, and submitted to the DBD via DBD e-Filing within one month of that approval. Keep each document paired with its ledger entry and check that the tax ID and registered name match on every page. Watch out: expenses without documentation identifying the recipient are commonly added back as non-deductible for corporate income tax. Verify current rules and forms with the Revenue Department (rd.go.th), the DBD (dbd.go.th), the Social Security Office (sso.go.th), the Federation of Accounting Professions (tfac.or.th) and the Department of Consular Affairs (consular.mfa.go.th). Professional fees are quoted per case based on document volume and scope — ask our team by phone, LINE or email. If financial statements or tax-payment certificates will be used abroad, plan translation and legalisation at the moment you request the documents, not afterwards. Verify forms and deadlines with the Revenue Department (rd.go.th) and financial-statement requirements with the Department of Business Development (dbd.go.th).

Full service playbook — Legal drafting & document review

Drafting and review start from the facts and the parties' objectives, then select the document structure, language and enforcement route that suit the destination.

Responsible authority: The responsible attorney and the authority relevant to the matter

Documents to prepare

  • Identity documents for every party, plus company affidavits for corporates
  • Underlying paperwork such as prior contracts, invoices or payment evidence
  • The commercial terms wanted — scope, term and termination conditions
  • Related title or registration documents where applicable
  • Requirements of the authority or country where the document will be used

Step-by-step process

  1. 1. Fact interview and objective setting1–2 business days

    Capture what each party needs and the risk each can accept before choosing the instrument.

  2. 2. First draft2–5 business days

    Draft parties, scope, consideration, term, termination and governing law.

  3. 3. Client review round1–3 business days

    Refine wording and reconcile defined terms across the whole document.

  4. 4. Bilingual version for overseas use1–3 business days

    Produce a Thai–English version stating which language prevails.

  5. 5. Execution and certification3–10 business days

    Sign before a notarial services attorney, then add an Apostille or legalisation if used abroad.

Practitioner tips

  • State the prevailing language explicitly to avoid interpretation disputes.
  • Keep negotiation records and emails as evidence of the parties' intent.
  • Check the destination's freshness rule first; many accept documents issued within the last 3–6 months only.
  • Confirm whether the destination wants an original or a certified copy — the two follow different routes.
  • Assemble the full set before filing once; batching is faster than submitting one document at a time.

Cautions

  • Website content is general information, not advice on your specific matter.
  • Copying a template without adapting the facts often leaves clauses unenforceable.
  • Do not write on, amend, or correction-fluid an official document; request a fresh copy from the issuing office instead.
  • Multi-page documents must be certified on every page where the rules require it, not only page one.
  • Never unstaple or re-bind a certified bundle — breaking the seal usually voids it and restarts the process.

Compare the options before you decide

Apostille route vs embassy legalisation route

The destination country decides whether a file ends at an Apostille or still needs the embassy. Confirm the country's convention status first: the two routes use a different order and different paperwork.

Thailand's notarial attorney vs a foreign Notary Public

Thailand has no Notary Public office in the international sense. Equivalent work is performed by a Notarial Services Attorney licensed by the Lawyers Council of Thailand.

AspectThailand: notarial attorneyAbroad: Notary Public
Who is authorisedAn attorney licensed for notarial services by the Lawyers CouncilA notary appointed by the state or a court
ScopeSignature certification, true copies, affidavits and translations where the law allowsVaries by jurisdiction
Usual next stepFile with the Department of Consular Affairs, then Apostille or embassyUsually the country's own central authority
In-person requiredYes — you sign in front of the certifying attorneyGenerally yes

Where the receiving body uses its own terminology, follow that wording rather than claiming an equivalent title.

Filing it yourself vs letting NYC run the chain

Every step can be done alone. This table compares the real workload of each option so the decision rests on time and rejection risk rather than marketing claims.

AspectDo it yourselfNYC handles it

TravelSeveral agencies with queues that rarely line up in one dayDocuments move by courier or online except where the law requires you in person

What the common mistakes actually cost

Almost every failure in legal instruments and drafting happens during preparation, not at the counter, and the real cost is the TIME needed to repeat the chain. Below is what each mistake comes from, how long it typically adds, and how to avoid it.

MistakeWhy it happensTime costHow to prevent it
Planning without allowing for public and embassy holidaysEmbassies close on both Thai and home-country holidays, so the real calendar is shorter than it looks.Typically adds 3–9 working days around a long holiday period.Check the holiday calendar of every body involved before fixing a travel or filing date.
Removing staples or separating pages after certificationThe certification is attached to the bound set; once separated the set counts as incomplete.Typically adds 3–7 working days to re-certify the set.Scan first, then keep the originals in a rigid envelope without detaching anything.
Self-translating, or using a translator the destination does not recogniseSome countries accept only registered translators, others only translations certified by a Thai government body.Typically adds 4–10 working days for a fresh translation and a restarted chain.Ask the destination exactly which form of translation it accepts, then match the translator to that form from the start.
Booking the wrong service channel or appointment typeEach channel has its own queue and document conditions; the wrong one means booking again.Typically adds 2–14 working days depending on appointment availability that month.Confirm the service type and the appointment date in advance and keep at least one spare week.
Running the chain in the wrong order — embassy before the consular departmentEach body only certifies the signature of the body immediately before it in the chain.Typically adds 5–12 working days and forces a re-filing from the skipped stage.Confirm the route with the receiving authority before starting, or have us map the chain up front.

Deep timeline: what can run in parallel

The windows below are approximate and depend on each authority's queue. Stages marked as parallel can start alongside the previous stage — that is where the total calendar time is actually reduced.

  1. 1. Advisory call to fix scope and form1–2 working days

    Parties, delegated powers, and the intended effect are settled before drafting to avoid later rewrites.

  2. 2. Drafting and professional review2–5 working days

    Wording, signing authority, and annexes are checked against what the destination requires.

  3. 3. Execution and certification1–3 working days

    Signatories appear with original identity documents and the instrument is certified in the required form.

  4. 4. Translation and legalisation for overseas use3–15 working dayscan run in parallel

    Possible once the original is fully executed; timing depends on destination and queues.

Note: all windows are general estimates, not guarantees. Actual timing depends on how complete your file is and on the queues at the authorities involved.

We work as advisers, not only as a document-running agency

Our team has worked on documents, translation and legalisation for more than 15 years, combining notarial attorneys licensed by the Lawyers Council of Thailand with translators the receiving authorities accept. Every case starts with advice on the correct route and only then moves to execution — we do not simply run whatever is handed to us.

Before we start — mapping the document route

We confirm whether your file ends at an Apostille or still needs the embassy, whether a freshly issued copy is required, and which form of translation the receiving authority accepts. This is where most time is saved, because it is where most people choose wrongly and restart.

While preparing — consistency checks

We match the spelling of your name against the passport, check the issue date against the validity window the destination applies, verify stamps and signatures, and confirm the translation matches the original line by line.

While filing — coordination with the authorities

We file in the order each authority expects, follow the queue, and report status as it moves. If an authority asks for more paperwork, you hear about it immediately, together with the options for fixing it.

After delivery — practical guidance

We explain which bodies this set can be filed with, how to store the originals, and how many certified sets to request up front if you expect to use them again, so you do not repeat the whole chain later.

Cases where advice up front changes the outcome

  • The name on an older document does not match the current passport because of a name change or a different transliteration.
  • Documents have a limited validity window and every item must still be valid on the day of filing.
  • The destination only says "certified translation" without stating which form of certification it accepts.
  • Documents are needed for several countries at once, each with a different order of certification.

If you are unsure which route your case takes, send photos of the documents and name the destination country or authority. We map the sequence and the paperwork first; you then decide whether to run it yourself or hand it over.

Accounting

Most delays in "Accounting" matters come from re-filing, not from the work itself. Our International Document Services team therefore verifies destination requirements first and only then walks the file through the accepted sequence. We handle files from Bangkok, upcountry, and overseas clients working through a power of attorney. Every matter has one named owner, with a Notarial Services Attorney (registered with the Lawyers Council of Thailand) performing the final certification review before release. Fees are itemized before work begins: professional service fee, government fees, domestic EMS, and international courier (DHL/FedEx). Choose standard turnaround of 5-7 business days or rush turnaround of 1-3 business days.

What to prepare before filing Accounting

  • Original document required for Accounting (or a freshly issued certified copy within its validity window)
  • Copy of national ID or passport, signed and dated as a true copy
  • Power of attorney (if a representative will handle it) with a 30 THB revenue stamp
  • Destination details: country, receiving authority, purpose, and required deadline

Accounting: the working sequence

  • 1. Send scanned copies of the Accounting source documents via LINE/email for a free initial review.
  • 2. We confirm eligibility and issue a written quote with a committed turnaround.
  • 3. You deliver originals to our office (or book a Bangkok pickup) and pay a 50% deposit.
  • 4. We translate, certify, and submit to each Thai authority in the order the destination accepts.
  • 5. Final documents are scanned and emailed for your review before physical dispatch.
  • 6. We ship by EMS domestically and DHL/FedEx internationally, with tracking numbers.

Turnaround and cost structure for Accounting

  • Standard turnaround for Accounting: 5-7 business days from receipt of complete originals.
  • Rush turnaround: 1-3 business days (rush surcharge applies).
  • Government fees are charged at official rates with no markup.
  • Domestic EMS at Thailand Post rates; international DHL/FedEx at actual weight-based rates.

Re-filing triggers in Accounting matters

  • Dates that disagree across documents — this must be fixed at the issuing agency; it cannot be corrected at the translation stage.
  • Originals outside the validity window — many destinations require documents issued within 3-6 months. Confirm with the receiving authority first.
  • Name mismatch between the document and the passport — embassies reject these. Correct it at the district office before translating.
  • Submitting an uncertified photocopy instead of the original — the receiving office will not review it and you rejoin the queue.

Common Pitfalls (From Field Experience)

  • Filing financial statements after the statutory deadline and incurring penalties.
  • Using a translation whose figures differ from the filed financial statements.
  • Not retaining supporting accounting records for the statutory period.
  • Assuming a company with no revenue need not file — the filing duty still applies.

Compare the options before you decide

Apostille route vs embassy legalisation route

The destination country decides whether a file ends at an Apostille or still needs the embassy. Confirm the country's convention status first: the two routes use a different order and different paperwork.

5 accounting and tax mistakes that trigger assessments

Most issues come from weak expense documentation and late filings.

  1. 1. Incomplete or invalid expense documentation

    Why it matters: Unsupported expenses can be added back.

    How to avoid it: Keep valid tax invoices matching the actual payer.

  2. 2. Mixing personal and business spending

    Why it matters: It distorts financial statements and tax.

    How to avoid it: Use a separate business bank account.

  3. 3. Late or wrong-form filings

    Why it matters: Surcharges and penalties apply by law.

    How to avoid it: Keep a monthly tax calendar and verify the form type.

  4. 4. Failing to withhold tax when required

    Why it matters: The payer remains liable for unwithheld tax.

    How to avoid it: Check income type and rate before every payment.

  5. 5. Closing books too late to review

    Why it matters: Rushed closings hide errors that are hard to fix later.

    How to avoid it: Close monthly rather than annually.

What the common mistakes actually cost

Almost every failure in legal instruments and drafting happens during preparation, not at the counter, and the real cost is the TIME needed to repeat the chain. Below is what each mistake comes from, how long it typically adds, and how to avoid it.

MistakeWhy it happensTime costHow to prevent it
Using an old copy instead of a freshly issued oneMany destinations accept documents issued within the last 3–6 months only, and some require a clean, legibly sealed reissue.Typically adds 5–15 working days for the trip back to the district registrar.Check the destination's freshness rule first, then request several certified copies in a single visit.
Planning without allowing for public and embassy holidaysEmbassies close on both Thai and home-country holidays, so the real calendar is shorter than it looks.Typically adds 3–9 working days around a long holiday period.Check the holiday calendar of every body involved before fixing a travel or filing date.
Booking the wrong service channel or appointment typeEach channel has its own queue and document conditions; the wrong one means booking again.Typically adds 2–14 working days depending on appointment availability that month.Confirm the service type and the appointment date in advance and keep at least one spare week.
Filing an incomplete set — missing an ID copy or a power of attorneyCompleteness is checked at the counter; an incomplete file is not accepted at all.Typically adds 1–5 working days per return trip.Work from a written checklist and re-check it before leaving, including every copy that needs a signature.
The name in the translation does not match the passport spellingReceiving authorities compare character by character; a single different letter reads as a different person.Typically adds 3–10 working days, because the translation has to be redone and the whole chain repeated.Send the passport page on day one and have the translator take the spelling from the passport, never from the Thai document.

Most cases need more than one step. Here is how the surrounding work connects, so you can plan the whole chain instead of discovering a missing certification at the last minute.

Not sure which of these your case actually needs? That is exactly what our advisory team does: with 15+ years on cross-border documents, we map the full chain for your destination first, then handle every step so nothing is filed in the wrong order.

We work as advisers, not only as a document-running agency

Our team has worked on documents, translation and legalisation for more than 15 years, combining notarial attorneys licensed by the Lawyers Council of Thailand with translators the receiving authorities accept. Every case starts with advice on the correct route and only then moves to execution — we do not simply run whatever is handed to us.

Before we start — mapping the document route

We confirm whether your file ends at an Apostille or still needs the embassy, whether a freshly issued copy is required, and which form of translation the receiving authority accepts. This is where most time is saved, because it is where most people choose wrongly and restart.

While preparing — consistency checks

We match the spelling of your name against the passport, check the issue date against the validity window the destination applies, verify stamps and signatures, and confirm the translation matches the original line by line.

While filing — coordination with the authorities

We file in the order each authority expects, follow the queue, and report status as it moves. If an authority asks for more paperwork, you hear about it immediately, together with the options for fixing it.

After delivery — practical guidance

We explain which bodies this set can be filed with, how to store the originals, and how many certified sets to request up front if you expect to use them again, so you do not repeat the whole chain later.

Cases where advice up front changes the outcome

  • The applicant is upcountry or abroad, so the power of attorney and courier plan must be arranged carefully.
  • The name on an older document does not match the current passport because of a name change or a different transliteration.
  • Documents have a limited validity window and every item must still be valid on the day of filing.
  • Documents are needed for several countries at once, each with a different order of certification.

If you are unsure which route your case takes, send photos of the documents and name the destination country or authority. We map the sequence and the paperwork first; you then decide whether to run it yourself or hand it over.
