Hi, my father is coming to Thailand in December, and will enter on the visa exemption stamp. I believe that means he can stay 45 days, as he is British.
How many times can that be extended in Chaengwattana, and therefore what would be the total time he could stay before heading back to the UK?
TIA
TLDR : Answer Summary
A British citizen entering Thailand on a visa exemption stamp can stay for 45 days initially. He is eligible to apply for one 30-day tourism extension at the immigration office at IT Square Laksi Plaza, which allows for a total possible stay of 75 days before needing to return to the UK.
