When my daughter got into Australian University, opening her bank account, with the ANZ bank. They insisted on her Tax File Number. She had a Japanese version of it, called "MyNumber". ANZ recognized it, a world standard and she was OK.
My Thai wife, BKK Bank Account, got her ATM card swallowed (2019) by the ATM machine. Bang Na, Bangkok.
The branch staff told her, she has to go to the original branch where the account was created (year 2000). Rama 4, Khlong Thoey, Shopping Mall to retrieve it. She had to go there (still, it is Bangkok, no intercity travel).
Immigration Officers do not calculate anything on the spot. It is ready for them to see on their computer screens, automated. Then, their discretion, to do nothing and let you in or warn you for the next time or even worse, deny the entry.
When I applied for Yellow Book (Bangkok, Samut Phrakhan), there was a question: "How many extensions I have had over last 25 yers". Zero, the officer just nodded.
So I guessed. I have Non O visa that kicked in July 26. 2025. Next time in Thai, October 2025, I will insist on that TM30 at the airport. There are some more admin things to do, someone might ask me for the TM30 form.
25 years going to Thai, 3-4 times a year, never heard of TM30 until I joined this group.
I am the apartment owner, where do I find TM30 form to report myself? At the airport? There is a site, online, I submitted it 3. July 2025, it has been sitting there as "Processing", even a month after I left Thai.
Does anyone actually give a fcuk about TM30, other than hotel/accomodation establisments?
Edit: does not my Thailand Digital Arrival Card, that has my address in Thai, represent that TM30?
