Some years ago I was on an extension of stay based on employment then at the IO's advice I changed the reason based on married to Thai man. My husband passed away suddenly last week. Can I revert back to extension of stay reason based on employment? I asked immigration today but he was a bit cautious and just said "let's check documents first from my employer". I hope I don't have to leave the country!
TLDR : Answer Summary
The original poster (OP) is seeking advice on whether they can revert back to a one-year extension of stay based on employment, following the recent passing of their husband who was Thai. They initially changed their visa status to an extension based on marriage. The commenters confirmed that the OP retains the right to stay on the marriage extension until its expiry before needing to apply for another type of extension. They also discussed the necessary documents from the employer, which would facilitate a potential change in visa status. Overall, the OP seems to have rights under Thai immigration law that allow them to remain in the country until their current extension expires.
