My parents are visiting us from the US and got a 30 day visa but are actually staying 37 days. We thought it would be simple enough to extend it a week but it’s actually becoming quite complicated. They are flying to Chiang Mai on Sunday which is the day their visa expires and it looks like we aren’t going to be able to get the extension approved before then. Is this something they can do at the airport? What are the consequences if their tourist visa lapses before we get it figured out? Any tips on getting the extension? I have a 3 week old baby and feel like my head is spinning trying to figure this out!
