What should I tell the immigration office if I'm still staying in a hotel and need proof of residence to open a bank account?

The user is asking about the requirements for obtaining a proof of residence from the immigration office while staying at a hotel, which they need to open a bank account in Thailand. Several comments provide guidance, including the fact that a Certificate of Residence is generally given after at least one 90-day report is completed. However, there are instances mentioned where it might be possible to receive documentation without the 90-day report, suggesting that updating the address at the hotel could suffice. Additionally, users indicate that some banks may allow account openings with just a passport.
