Hello,
We have a 45 day trip scheduled for later this year - all in Thailand. With the visa-on-arrival changing to 30 days for US citizens, I’m looking for advice. The back end of our trip is all smaller islands (ie, no Thai immigration offices). My specific question is how early in the trip can I apply for an extension to the original 30 days? We will be in Samui 15 days into the trip and in Samui again 23 days into the trip. Does anyone know if Thai Immigration would process the extension at that point? Alternatively, can I apply for the extension immediately after I arrive in Bangkok at the beginning of our trip? Thank you in advance for any help or advice.
