Question about stamp. I have a non b single (90 days) with a multientry stamp. My visa is valid to 7 may. When I now arrived in Thailand 28 Feb my stamp say admitted untill 7 may. Should I not suppose to get 90 days on the stamp? Or do I still have 90 days? If I leave Thailand again and come back let's say 1 may will I get 90 days or just 6 until 7 may when the visa "expire"?
