monthly income is more complicated, you need to show the funds for the previous year before you apply for an extension, as well you need to have your embassy provide a letter certifying the income, or a letter saying they don't do income certification. The amount must be at least 65,000 baht per month each and every month and it cannot drop below that amount each month ever. I'm open to that I made a few mistakes in this, if so I'm sure Tod or Benjamin will correct me.
