Hi, is it possible to arrive into Thailand on the Visa exemption (30 days) and then extend that visa 7 days at an Immigration office? I will need to stay for 33 days after arriving from Bali, but worried that Thai officials may look suspiciously on the fact that I've been in Thailand 3 months before that. What do you think about this approach, would it be fine? I'm going back to my home country after these 33 days.
