I have a 6-month METV multientry visa, but I read that it is valid from the moment the visa is issued.
I don't know so because the other times the 180 days started the moment I entered Thailand,What do you think?
TLDR : Answer Summary
A 6-month METV (Multiple Entry Tourist Visa) is valid from the moment it is issued, according to community responses. While the visa allows entry into Thailand, the duration of stay begins from the entry stamp, not the visa issue date. Users mentioned that one can tactically manage entries to extend the stay, but the visa's lifespan is different from the allowed duration of stay upon each entry.
