Ah, so it is only of use if I have a visa with lots of time remaining and I want to leave and come back without applying for a new visa and voiding my current one?
I’m planning on staying in Laos for 3 days. When I come back into Thailand will I simply get another tourist visa or do I need to go to the Thai embassy in Laos first? Sorry for all the questions, it’s my first time doing this. I am going to apply for a retirement visa in a few months as I need to go back to the UK at the end of July regardless so I planned on starting the process at the Thai embassy in the UK in the hope that it will be easier without the language barrier.
