Basic requirements are (for teacher): Letter from school saying why it is urgent for you to come to Thailand, work permit, $
*****
0 US medical insurance covering COVID and COVID tests showing you do not have it. You can currently only fly on repatriation flights coordinated by the embassy and you have to pay for a 14 day quarentine at a government specified hotel upon arrival.
You need to contact the Thai Embassy in Indonesia and ask how to apply for permission to enter Thailand. There are many requirements which you can find by searching is some of the FB groups focusing on foreigners stranded outside Thailand. However every embassy has a slightly different process so you need to talk to them.
If you were married outside of Thailand then you need a "recent: Kor Ror 22 as well. What recent means depends on the individual immigration office (I have hear reports of everything from the same day to within 1 year) so check with your office.
You may be able to apply for a 60 day visit family extension after you are married if you can get all the required paperwork together in time to apply for it before the amnesty runs out. No financial requuremrnts. Check with your local immigration office. Not sure if you can then apply the nonO in Thailand or not during the 60 day extension.
You may need to register your marriage in Thailand first if you havent done that yet (required in Samatprakan for sure, we were married in US). This requires getting you marriage cert translated into Thai and then legalizing a copy (first legalized/authenticated by your embassy and then by the MFA in Thailand, then registering with local amphur office).
I think we need to wait and see what the official announcements are. Certainly they understand the boarder issues. I am hoping they will announce some kind of internal options for people still here (get 90day stamp for a valid ME visa without leaving Thailand, purchase a further extension within Thailand, covert to non b if you have a job etc). That seems more likely to me then reopenong boarders with other countries for bounces or other visa runs since that would take 2 governments to agree to in a short timeframe.
Samut Prakan Immigration requirements for extension of stay. Orange highlighted section is for 60 days for visiting family. Whole page is for 1 year extension due to marriage.
I visited tje Samut Prakan office yesterday and I was told the same as Todd wrote by the IO (bank book update same day as you apply, bank letter can be up to 7 days earlier). Will post a picture of their requirement list below (Thai only). The entire list applies for the 1 yeat extension due to marriage, the orange highlighted section is what is needed for a 60 day extension to visit family.
Also we gave tons of paperwork - a stack maybe 3cm high of proof of knowing each other (pics, travel records etc) - seemed to help as all the ICE folks commented on it (and didnt want to read it all) but we never had any questions about if we knew each other. Best of luck.
