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

342. How are the daily rates calculated for hiring a part-time French interpreter for a 3-day exhibition?

Interpreters are matched to the setting: court and police station, government and embassy, medical, simultaneous booth work, and remote VRI/OPI. 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.

508. What are the benefits of subscribing to an Annual Expat Concierge membership for managing visas and government paperwork?

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. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

393. How many days does an expat have to leave the country after canceling a work permit, and can you help request an extension?

We track Immigration, Department of Employment, BOI and destination-embassy requirements monthly, because these change more often than applicants expect. Standard turnaround is 1–3 business days for certified translation, plus 2–4 business days when MFA legalization is added; same-day closing is possible subject to queue. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

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

Company name, director names and registered address are cross-checked across every document, because a single spelling mismatch triggers a rejection. Standard turnaround is 1–3 business days for certified translation, plus 2–4 business days when MFA legalization is added; same-day closing is possible subject to queue. Tell us where the document will be used and you will get a plan and a price the same business day.

553. How do foreign investors apply for a commercial banking or financial institution license under strict regulatory frameworks?

Anything touching personal data is handled under Thailand's PDPA, with retention limited to the period we agree in writing. 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. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

413. Do you have lawyers to draft Non-Disclosure Agreements (NDA) and Distribution Agreements for international business?

Tax and land-registry documents carry terminology that cannot be paraphrased, so we work from Revenue Department and Land Department glossaries. 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.

441. Do you provide company name change and corporate seal amendment services, including notifying the Revenue Department and banks?

We route each file to the right credential: NAATI for Australia, Ministry of Justice registered translators for Thai court work, and embassy sworn translators for European destinations. One coordinator owns the matter end to end and reports progress by LINE or email at the intervals you set. Send your documents for a free assessment at +66-83-249-4999 or contact@nyconlinetranslation.com.

401. Where to find monthly bookkeeping and annual financial statement closing services for foreign companies using Xero 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. Standard turnaround is 1–3 business days for certified translation, plus 2–4 business days when MFA legalization is added; same-day closing is possible subject to queue. Tell us where the document will be used and you will get a plan and a price the same business day.

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

Electronic documents must be traceable to their source, so deliverables ship with an audit trail whenever the receiving party asks for one. Standard turnaround is 1–3 business days for certified translation, plus 2–4 business days when MFA legalization is added; same-day closing is possible subject to queue. Talk to the NYC Legal team on any business day — you get a working plan, not a generic price list.

568. What employment tax incentives apply to specialized foreign researchers working in BOI-approved tech parks?

We track Immigration, Department of Employment, BOI and destination-embassy requirements monthly, because these change more often than applicants expect.
