What documents are needed for a re-entry stamp when applying for a visa extension in Thailand?

When applying for a visa extension and simultaneously requesting a re-entry permit in Thailand, you need to submit specific documents along with your completed TM.8 application. Required documents include copies of your passport's data page, your new yearly extension stamp, your most recent entry stamp, and your TM.6 departure card. Additionally, a passport-sized photo and the appropriate fee (1000 baht for a single entry or 3800 baht for a multiple re-entry) are necessary to obtain the re-entry permit.
