They want you to do the TM30 report. You will need a letter confirming ypur address and a copy of the landlords ID. It should of been done within 24 hours of arriving.

James Miller he asked the minimum income per month. It's 65k baht per month. The minimum 'income' doesn't have to add up to 800k baht if your income is 65k Baht per month.
