Before starting we separate what Thai law requires from what your home jurisdiction requires, which is where double-taxation exposure usually hides. Government fees follow each authority's published rate, while professional fees are quoted per case by document count and destination, in full before work starts. 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. Caution: government fees follow the authority's published rate and are separate from professional fees; check the current rate on the official website first. 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. Private documents such as powers of attorney or contracts must first pass a notarial services attorney before they can enter the legalisation stage. Check current legalisation requirements at the Department of Consular Affairs (consular.mfa.go.th) and Apostille membership at hcch.net.

For proceedings that go on the record we staff paired interpreters rotating every 20–30 minutes, per international conference practice. Government fees follow each authority's published rate, while professional fees are quoted per case by document count and destination, in full before work starts. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com. 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. 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.

M&A and fundraising work demands speed and confidentiality, so we sign the NDA before intake and ring-fence a closed team for the matter. 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.

Filings for regulators are certified to the tier the regulator specifies, not the tier that happens to be familiar. Quotations separate government fees from professional fees line by line, so nothing appears on the invoice that was not in the quote.

Certification tiers are separated up front — agency Certified True Translation, Notary Public seal, MFA consular legalization, and Apostille (not yet available in Thailand — accession deposited 30 Jun 2026, in force 28 February 2027). If the receiving authority rejects a file for a reason attributable to our work, we correct and re-file it at no additional professional fee.

Space, satellite, quantum and holding-structure work uses terminology that is still settling, so we agree a glossary with your advisers before drafting begins.

A person present in Thailand for an aggregate of 180 days in a tax year is a Thai tax resident under section 41 of the Revenue Code, and may request a certificate of residence (form R.O.21) from the Revenue Department in order to claim double-tax-treaty benefits. Check first whether the receiving office accepts online submission or requires attendance in person, since individual Immigration offices differ in practice. Watch out: leaving Thailand without a re-entry permit immediately voids an existing permission to stay. Verify current requirements with the Immigration Bureau (immigration.go.th), the Department of Provincial Administration (bora.dopa.go.th), the Department of Land Transport (dlt.go.th), the Department of Employment (doe.go.th), BOI/LTR (ltr.boi.go.th), the Revenue Department (rd.go.th) and the Department of Consular Affairs (consular.mfa.go.th). Service fees are quoted per case based on scope and documents involved — ask our team by phone, LINE or email. In practice work backwards from the destination: confirm the document list with the office that will receive the file, then plan the order in which documents are obtained, translated and certified. Check the Immigration Bureau (immigration.go.th), the Department of Provincial Administration (bora.dopa.go.th) and document legalisation at consular.mfa.go.th.

If the permitted stay is close to expiry, allow time for certification, translation and appointment booking. Watch out: foreign-issued documents must complete the correct legalisation chain before a Thai authority will accept them. Verify current requirements with the Immigration Bureau (immigration.go.th), the Department of Provincial Administration (bora.dopa.go.th), the Department of Land Transport (dlt.go.th), the Department of Employment (doe.go.th), BOI/LTR (ltr.boi.go.th), the Revenue Department (rd.go.th) and the Department of Consular Affairs (consular.mfa.go.th).

Executive document work usually chains several authorities: translation, legalisation at the Department of Consular Affairs, embassy submission, then Immigration or the Department of Employment. Sequencing the chain and issuing the right powers of attorney up front avoids repeat trips. Keep the bundle paired original-to-Thai-translation, with signed copies of every relevant passport page. Watch out: mismatched name spellings across the passport, the translation and Thai records are the most common cause of re-filing. Verify current requirements with the Immigration Bureau (immigration.go.th), the Department of Provincial Administration (bora.dopa.go.th), the Department of Land Transport (dlt.go.th), the Department of Employment (doe.go.th), BOI/LTR (ltr.boi.go.th), the Revenue Department (rd.go.th) and the Department of Consular Affairs (consular.mfa.go.th). Service fees are quoted per case based on scope and documents involved — ask our team by phone, LINE or email. Anything with a statutory deadline, such as address notification or a permit renewal, should be diarised in advance with a spare document set ready, because late filing affects status directly. Check the Immigration Bureau (immigration.go.th), the Department of Provincial Administration (bora.dopa.go.th) and document legalisation at consular.mfa.go.th.

A foreigner permitted to stay beyond 90 days must report their address every 90 days under section 37(5) of the Immigration Act B.E. 2522. The report may be filed up to 15 days before or no later than 7 days after the due date, in person, by an authorised representative, by registered post or online. Keep the bundle paired original-to-Thai-translation, with signed copies of every relevant passport page.

Driving licences are issued by the Department of Land Transport. Foreign applicants present a passport with a qualifying non-tourist visa, a certificate of residence from Immigration or their embassy, and a medical certificate. Holders of a valid foreign licence may be exempted from certain tests under the Department's regulations. Keep the bundle paired original-to-Thai-translation, with signed copies of every relevant passport page. Watch out: failing to file the TM30 or the 90-day report on time carries a fine under the Immigration Act and can affect the next extension application. Verify current requirements with the Immigration Bureau (immigration.go.th), the Department of Provincial Administration (bora.dopa.go.th), the Department of Land Transport (dlt.go.th), the Department of Employment (doe.go.th), BOI/LTR (ltr.boi.go.th), the Revenue Department (rd.go.th) and the Department of Consular Affairs (consular.mfa.go.th).

Keep the bundle paired original-to-Thai-translation, with signed copies of every relevant passport page. Watch out: foreign-issued documents must complete the correct legalisation chain before a Thai authority will accept them. Verify current requirements with the Immigration Bureau (immigration.go.th), the Department of Provincial Administration (bora.dopa.go.th), the Department of Land Transport (dlt.go.th), the Department of Employment (doe.go.th), BOI/LTR (ltr.boi.go.th), the Revenue Department (rd.go.th) and the Department of Consular Affairs (consular.mfa.go.th).

Extensions of stay are filed at the Immigration office covering your area before the current permission expires. If you leave Thailand during a valid permission you must first obtain a single or multiple re-entry permit, otherwise the permission to stay lapses on departure. A workable order is: confirm the current visa status and the remaining deadline, gather originals with translations, then book an appointment and file with the office responsible for your registered address.

Watch out: foreign-issued documents must complete the correct legalisation chain before a Thai authority will accept them. Verify current requirements with the Immigration Bureau (immigration.go.th), the Department of Provincial Administration (bora.dopa.go.th), the Department of Land Transport (dlt.go.th), the Department of Employment (doe.go.th), BOI/LTR (ltr.boi.go.th), the Revenue Department (rd.go.th) and the Department of Consular Affairs (consular.mfa.go.th).
