What documentation is required for a Non-B visa re-entry permit application in Thailand?

To apply for a re-entry permit for a Non-B visa extension, you typically need to provide the TM 8 application form, signed copies of your passport photo page, the latest visa extension stamp page, the TM 6/Departure card, and possibly a copy of your 90-day report and/or TM 30. Additionally, you will need a passport photo and the applicable fee (1,000 THB for a single entry or 3,800 THB for multiple entries).
