Got stopped last night at Don Muang Airport. I have several 30 day exempt stamps that I have extended in my passport. Every time we flew out for a week or so to do some travelling. This specific immigration officer was giving quite a few people a hard time by asking loads of questions as our queue moved very slowly compared to the other 2 counters. He flicked through my passport and saw my stamps and asked me for a return ticket to my home country, normally its just an onward ticket. Didn't have a ticket to my home country and he called another immigration officer who took me to a booth on the right just before you go down the stairs. The lady scanned my passport and looked on the computer and told me that I have been here for +- a year and she needs to see a return ticket to my home country. Told her I don't have one but I can buy one right now which lighted the situation. Quickly went on Skyscanner and bought a ticket to my home country (I'm anyway going home in 7 weeks) and showed her the ticket on my phone which is in 7 weeks so I will need another extension which wasn't a problem at all. She made some notes and wrote down my new flight number and stamped me in. Didn't ask for 20k or proof of address (I did have both).
TLDR : Answer Summary
A traveler shared their experience at Don Muang Airport where they faced scrutiny from immigration due to having several extended 30-day visa exemption stamps. The officer requested a return ticket to their home country, which is not typically required, and after some delay, the traveler was able to purchase a ticket online to avoid being denied entry. This incident sparked discussions about immigration policies, the rights of immigration officers, and the typical requirement of showing onward travel versus a return ticket.
