How does staying with my son in Thailand on a Non-OA visa affect my TM30 and opening a bank account without a lease?

I entered last month on a non O-A and found opening a bank account very easy. If your son owns the property he must file TM30 with immigration. If he is a tenant his land lord must.

To get a residence certificate you need to attend immigration with TM30, your passport with signed photocopies of data page and stamp page. You need to complete a form , have a passport size photo and the fee is 500 baht ( that was at Phuket , may vary from place to place) You can get a residence certificate on day one in Thailand.

All banks vary with their requirements. Some vary from branch to branch in same banking group.

I used BKK bank in Karon Phuket and needed Passport , Thai SIM card , home country address , home country UTR and driving licence. As I didn’t have a Thai DL they accepted home country DL as I had an IDP ( international driving permit) I would suggest you get one before you travel from your home country. The whole experience lasted 45 mins. But as I say different branches of the same bank may have different requirements. After all TIT ( this is Thailand)

I was never asked for residence certificate or tenancy agreement. Best to check with your preferred bank first and when you go back try to see the same person you checked with.

Hope this helps

You're probably okay because you have a 12 month visa. Make sure your son files the tm-30 each time you return to stay with him. You can most likely get a residency certificate from that tm-30 but probably good too have him write a letter that you are staying with him long term. Immigration like documentation...

Take all that with you too the bank. Dress reasonably and act professionally and if you don't get an account at the first bank, try another. Use the main branches in the town you're living in.

If you are staying with your son have him do a TM 30 showing that you live with him. Having a Non O visa already should make it easier to get a bank account. Just make sure you get a Certificate of Residency from Immigration when the TM 30 is approved.
