I have a Non- Im B Multi, I want to apply for a one year extension of stay based on marriage, (I know about the money in account/income requirement etc) I believe I have to exit and re-enter on another type of visa, what’s the exact process for this. Work permit expires mid Sep (being renewed) visa in mid Oct. also 😬 how will it work as far as my WP is concerned? As far as if it’s issued whilst under one visa, will it be valid under a one year extension based on marriage or will I have to do/declare/apply for or modify anything?
TLDR : Answer Summary
To apply for a one-year extension of stay based on marriage with a Non-IM B Multi visa, you must first exit Thailand and apply for a single-entry 90-day non-immigrant type O visa at a Thai consulate. After receiving the visa, return to Thailand and get stamped in for 90 days. Within the last 30 days of your stamp, you can then apply for the one-year extension while meeting the necessary financial requirements. Your work permit renewal should be coordinated; it typically remains valid if issued while on the previous visa, but it's advisable to check specific regulations regarding modifications.
