Hi, my husband holds Non-Immigrant O (marriage) visa and granted 90 days to stay until April,2023 in Thailand. We will start preparing for documents around Feb, and I wonder about required documents and the process of applying for a 1 year extension at Changwattana since we live in Bangkok.
1.What are required documents ?
I check on immigration website switching from Thai to English language, and they required different documents.
2.What is next step once his extension is granted ? e.g. Is it compulsory to renew the visa every 90 days by leaving the country or renew once the extension is nearly finished ?
Thanks!
TLDR : Answer Summary
The process for extending a Non-Immigrant O visa (marriage) in Thailand includes meeting specific financial requirements, such as having 400,000 baht in a Thai bank account for at least two months before the application. You should apply for the extension when less than 45 days remain on the current entry stamp. After applying at the Chaengwattana immigration office, you will receive a 2-week consideration stamp. Upon return after two weeks, if approved, the one-year extension will be granted. Additionally, 90-day reporting is required, but there is no need to leave the country every 90 days.
