ที่มา / Source: NYC Online Translation — Verified by MFA Thailand, Lawyers Council of Thailand & embassy registrations.
NYC Legal processes 50+ US Citizen-Thai marriage filings per year. Our team understands the exact intake routine of the US Citizen embassy in Bangkok and the documentation expectations of Thai district offices for US Citizen spouses.
The critical document for US Citizen nationals is "Affidavit of Marriageability at US Embassy Bangkok". You must appear in person at the embassy — we book the slot, brief you, and accompany you on the day.
Once issued we (1) translate via a Consular-Affairs-registered translator, (2) legalise at MFA Chaeng Watthana (2-3 working days), (3) book the Amphur of your choice anywhere in Thailand (Bangkok 50 districts or any of 77 provinces), provide a certified interpreter and two witnesses on filing day, then (4) translate the resulting Kor.Ror.2/Kor.Ror.3 back into English with apostille for use in the United States.

Frequently asked questions
What does the US Citizen embassy charge?
at the official rate depending on country — we confirm the exact fee after eligibility check.
What if the US Citizen spouse was previously married?
You need the divorce decree apostilled/legalised and translated into Thai — we handle this end-to-end.
Can I marry on a tourist visa?
Yes — Thai law does not restrict visa type for marriage registration. We recommend converting to Non-O Marriage afterwards if you plan to stay.
Can I get the Non-O Marriage visa right after?
Yes — immediately after Kor.Ror.2/3 is issued. Add-on service (ask staff for the current fee)
Which Amphur should I use?
Any district nationwide — Watthana, Bang Rak, Pathum Wan handle foreigner filings most smoothly.

481. Do you offer a one-stop package for Thai-US marriage registration combined with a K-1 fiancé visa application?
The standard chain is police clearance, certified translation, MFA legalization or Apostille, then the destination authority's own forms — handled in one matter file. 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@nyclegal.co.th. 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: 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: 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.

356. Can an agency manage the bank deposits and health insurance requirements for a foreigner's O-A/O-X retirement visa?
Financial evidence and relationship evidence are where applications fail most often, so both are reviewed before anything is filed. 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. Private documents such as powers of attorney or contracts must first pass a notarial services attorney before they can enter the legalisation stage. Caution: processing time depends on each authority's queue, so allow buffer before the date the document is actually needed. 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: 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. Request more than one certified set when several authorities are involved, because most receiving offices keep the certified copy and do not return it.
