International Document Services

Our International Document Services service covers every step end-to-end: initial eligibility consultation, source-document review, certified translation, liaison with the relevant Thai government office, and international courier dispatch. The handling team includes attorneys registered as Notarial Services Attorneys with the Lawyers Council of Thailand, translators recognized by the Ministry of Justice, and consular liaison officers with 10+ years of experience. Every document carries a different downstream use case — employment, study, immigration, marriage, or commercial filing — and each receiving authority has its own acceptance rules. We plan the shortest and most cost-effective document routing for your case before any fees are charged, and we issue a written timeline so you can schedule your travel or filing with confidence. Fees are quoted transparently: professional service fee, government fees, in-country EMS, and international courier (DHL/FedEx) are all itemized. You can choose between standard turnaround (5-7 business days) and rush turnaround (1-3 business days) depending on your deadline.

Cross-service questions, answered by the NYC Legal team

599. How do companies secure approval for importing specialized industrial machinery duty exemptions via BOI?

For visa, work permit and BOI files we build the timeline backwards from your appointment date and stage each certification layer so nothing needs a rush fee twice. Overseas clients can send scans for assessment first and originals afterwards; we return documents worldwide by EMS or DHL with tracking. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

537. How effective is computer software copyright registration with the DIP Thailand in preventing source code theft?

The whole workflow runs online, so clients abroad do not need to fly back to Thailand to sign every page. Indicative fees: certified translation THB 500–800 per page, consular legalization from THB 400 per stamp, Notary Public from THB 1,500 per signature — always quoted in full before we start. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

443. If a foreign company lacks an HR department, can your agency handle payroll, expat visa renewals, and P.N.D.1 tax filings entirely?

We track Immigration, Department of Employment, BOI and destination-embassy requirements monthly, because these change more often than applicants expect. Quotations separate government fees from professional fees line by line, so nothing appears on the invoice that was not in the quote. Tell us where the document will be used and you will get a plan and a price the same business day.

574. What intellectual property safeguards apply when outsourcing software development to Thai tech agencies?

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. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list.

266. Where is the official list of Swiss and Austrian embassy sworn translators in Thailand?

Every certified file passes three hands: a native-speaking translator, a subject-matter reviewer, and the responsible attorney who signs the certification page. 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. Tell us where the document will be used and you will get a plan and a price the same business day.

477. How much does an Annual Expat Concierge subscription cost to act as a personal assistant for visas, housing, and government affairs?

Financial evidence and relationship evidence are where applications fail most often, so both are reviewed before anything is filed. One coordinator owns the matter end to end and reports progress by LINE or email at the intervals you set. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list.

331. Can a Thai citizen applying for a restaurant job in Australia request a Police Clearance and NAATI translation together?

Certification tiers are separated up front — agency Certified True Translation, Notary Public seal, MFA consular legalization, and Apostille (in force for Thailand since 14 Nov 2024). Quotations separate government fees from professional fees line by line, so nothing appears on the invoice that was not in the quote. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

505. Where can foreign executive families in Thailand source English-speaking maids or private drivers?

The whole workflow runs online, so clients abroad do not need to fly back to Thailand to sign every page.

Tell us where the document will be used and you will get a plan and a price the same business day.

533. How many founding members are required to officially register a trade association or charitable foundation in Thailand?

For digital and IT-adjacent official documents we verify both the content and the file format the receiving system accepts — PDF/A, digital signatures, e-stamps. Indicative fees: certified translation THB 500–800 per page, consular legalization from THB 400 per stamp, Notary Public from THB 1,500 per signature — always quoted in full before we start. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list.

528. What safety regulations and location requirements govern gem and jewelry trading business license registrations?

For import, export and special licences we keep the Board of Trade and agency template packs ready in advance.

Tell us where the document will be used and you will get a plan and a price the same business day.
