Where can I get my marriage license packet translated in Thailand?

There are several translation services on Wireless Road near the US Embassy in Bangkok. That is where we got ours translated. 😎

You can use Sawadee translation service they did mine and can get it stamped by the Thai ministry. It costs some money though about 6000 just go to there website for free quote and timeframe you can message the on line app

My wife and I are both American citizens. I have a Non O-A visa. She has her 2nd Non O 90 day visa from the Vientiane Thai Embassy because her application for the one year extension was rejected. Apparently the photocopy of our Colorado marriage license was fine for the e-visa system, but not for the extension application. We cannot find our original marriage license, we somehow lost it during our relocation. Because we don’t have the original, we have to go down the path you described: obtain a certified copy from the county clerk, have it authenticated by the CO Secretary of State, the State Department, and the Thai Consulate in LA. We have the first two steps done. We plan to use Sawadee Translations here in Bangkok to translate the authenticated license and obtain the legalization stamp from the Ministry of Foreign Affairs. Then we go to Immigration and apply again for the one year extension of my wife’s Non O visa. Moral of the story: don’t lose your original marriage license, keep it handy at all times.

Why don't you go ask Immigration ?

You can use any translator/translation service

These did ours including mfa registration

Have you sent it to the Thai Embassy in the US yet? I am just starting to do ours. From what I understand I send my Santa Cruz County embossed marriage certificate to the California Secretary of State’s office, then to the State Department certification office in Virginia, then the Los Angeles Thai Consulate. Take that with us to Phuket and take it to a certified translator. There are probably some in Los Angeles I would think since there is a large population of Thais there. There is a Ministry of Foreign Affairs office in Phuket where we live. They have to certify the translation and document. Then to the Amphur’s office with two Thai witnesses to confirm that you live together and are still married. Then they give you the Kor Ror 22 for immigration and your tax ID that you have to get from the Finance Ministry if you are in Thailand more than 179 days in a calendar year.

Immigration used to take a copy of our marriage certificate until after COVID. This new requirement is a pain in my ass! I may as well get a yellow book and pink card while I’m at the Amphur’s office…. Good luck! The US Consulate in Chang Mai no longer stamps or certifies marriage certificates from what I’ve read. Same thing for income affidavits like I used to be able to use.

Translation services are everywhere. Usually close by the legalization offices. It will cost around 200-300 ฿ per page. Don't forget to make a reservation for the legalization service and don't pay for the "expedited" service, as it is not a service that can be expedited and will be a waste of ฿400. Don't forget the last step which is the registration at an Amphur. That is the final step to have a fully legal marriage in Thailand and how you obtain your Kor Ror 2 and 3. The queue at most offices is well out into the future (2+ months).
