This question is for a good friend of mine:
Hello. I want to stay three months in Thailand this winter. I was thinking about using my marriage certificate and applying in England. However, I don't see my Thai wife anymore but we are not officially divorced. Any thoughts on that?
TLDR : Answer Summary
A user asks about visa options to stay in Thailand for three months, referencing their marriage to a Thai citizen, although they are no longer in contact. Multiple commenters suggest applying for a Single Entry Tourist Visa (SETV) or a Multi Entry Tourist Visa (METV), with explanations about the options and how to extend stay periods.
