I have a non-O visa from Belgium, valid for 90 days. I'm coming to Thailand in October. I've booked a hotel room for only one month. (After that, I want to stay with my girlfriend, but the room owner doesn't fill out a TM30 form, even though he's required to do so.) The hotel owner forwards the TM30 form to immigration. I have to report to immigration within 24 hours. Will I receive proof of residency from immigration, even though I've only booked a room for one month? I need this proof to open a Thai bank account to apply for a one-year extension at the end of the 90 days. Thanks in advance for your answers.
