I do this before one month in chiang mai ,it's not something difficult, just need little time,if you hurry can arrange a agent to do this for you ,I hope I helped you a little bit ,good luck krap 🙏
No need marry again, you need receive stamp from ministry of foreign affairs in USA and then stamp from thai embassy in USA, then you go to Thailand to receive stamp from thai ministry of foreign affairs, then go to your district and register your marriage
I understand him 👍copy your passport and just receive stamp from your ministry of foreign affairs and then stamp from thai embassy to can use it for legalize your marriage in Thailand
translate certificate of marriage in English, after go to ministry of foreign affairs to receive stamp and then go to thai embassy to receive stamp again...when you travel to Thailand translate English version in thai language and receive stamp from ministry of foreign affairs in Thailand, then find two witness and go to your wife's district to register your marriage, its easier if you do via some agent, translate and stamp cost around 1500 baht ,excuse me about my English
I do the same before 2 weeks ,we married in Greece before one year, its very easy process, need little time but nothing complicated...no forget to copy and receive Stamp for your passport
