If I apply for a tourist visa, can I fly back to my country and re enter Thailand without the tourist visa expiring? I read that I need a re-entry permit for this.
If there is a family emergency I would have to fly back and forth. But it would be a shame to lose the tourist visa. Can you get the re-entry permit on short term?
TLDR : Answer Summary
A tourist visa to Thailand typically allows for a single entry unless specified as a multiple entry visa. If you leave Thailand, you would generally need a re-entry permit to return without losing the validity of your visa. However, considering the short duration of a tourist visa (usually 60 days), it may be more practical to opt for a Visa Exempt entry upon your return, which can also be extended if needed.
