What are the steps to register my US marriage in Thailand and what is KORROR 22?

What a lot of administrative c$ap!

Copy and paste from an expert on this topic at ASN:

1: Obtain a certified copy of your marriage certificate. Contact the vital records office in the state where you were married to request a certified copy.

2. Send the certified copy to the Secretary of State in the state where the document was issued to get the document authenticated.

3. Forward the state-authenticated document to the U.S. Department of State's Office of Authentications.

4. Once authenticated by the US Department of State, submit the document to the Thai Embassy in the U.S. for final authentication. At this point, the document should have a final authentication seal from the embassy.

You need to complete all of these steps BEFORE you leave the US. You need the final authenticated document from #4 to take to Thailand. Once you arrive in Thailand, you have additional steps:

5. After entry to Thailand, make an appointment with the US Embassy to produce a 'certified' copy of your passport.

6. Take the authenticated US marriage certificate and the Embassy certified copy of your passport to a Thai translator for translation.

7. Submit the documents to Thailand's Ministry of Affairs for legalization.

8. Submit the certified, authenticated and legalized documents to an Amphoe to register your overseas marriage.
