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!
