Common reasons you need documents for Thailand
Work permits, long-stay visas, marriage, and business registration.
Documents and who authenticates them
Degrees, birth and marriage certificates, and notarized documents authenticated in the U.S., and FBI results authenticated by the U.S. Department of State.
Step by step from Oregon
- Check your deadline. Documents used before February 28, 2027 need legalization; later use may accept an apostille.
- Authenticate the document in the U.S. through the issuing state, and the U.S. Department of State when required.
- Have it legalized by a Royal Thai Embassy or Royal Thai Consulate General.
- Arrange the Thai translation the receiving office requires and submit your application.
Translation
Thai offices usually require a Thai translation. Ask the receiving office whether it must be certified in Thailand.
Good to know
- From February 28, 2027, an apostille is expected to replace legalization for U.S. documents used in Thailand. If your deadline is close to that date, ask the receiving office which it will accept.
Moving to Thailand: which route, and what it needs
Requirements differ by route and change without notice, so treat this as a starting point and confirm with the consulate or your immigration attorney.
- Work and employment. A job offer usually drives the paperwork. Employers and immigration offices commonly ask for a criminal background check, degrees, and sometimes birth or marriage records, all authenticated.
- Business, investor, and self-employment. Company formation, investor permits, and self-employment routes typically need authenticated corporate documents, powers of attorney so someone can act for you locally, and a background check.
- Remote work and digital nomad routes. Where a remote-work route exists, applications usually require proof of foreign income, health insurance, and an authenticated background check. Confirm whether the route is currently open before you build a document pack around it.
- Retirement and passive income. Retirement routes generally require an authenticated background check, proof of pension or investment income, health insurance, and often apostilled birth and marriage certificates.
- Family, marriage, and children. Marriage abroad, family reunification, and registering a child usually need apostilled birth and marriage certificates, and sometimes a single-status or no-impediment document.
- Study. Universities and student permits typically ask for apostilled diplomas and transcripts, and a background check for longer programs.

your appointment
We capture your prints and submit the request through our channeler partners. The FBI controls how quickly results come back. - Notarization, if your documents need it — Same day
Powers of attorney, affidavits, and copies that need a notary before authentication are handled at your appointment, in our office or at your location. - Apostille or authentication courier service — 10 to 15 business
days

Ordered after the apostille when the receiving country wants the apostille page translated too. Some countries require their own sworn translator, and we tell you when that applies. - Your consulate appointment — Set by the consulate
Book early. Appointment backlogs, not document preparation, are usually what delays a move.
Finding the Thailand consulate that covers Oregon
Each Thailand consulate in the United States covers specific states, and you generally have to file with the one that covers Oregon. Check the consulate's own website for its jurisdiction, appointment system, and current document checklist, because those differ by post and change without notice.
The U.S. State Department publishes the official directory of foreign consular offices in the United States, which is the reliable place to find current addresses and contact details rather than a third-party list.

We don't book consulate appointments or file applications. We prepare, notarize, translate, and courier the documents you take to that appointment.
