Come see me on Thursday. You’ll need a copy of your passport data page, a copy for your entry stamp (both signed) a photograph and a filled out TM7 (you can download prior or get there). If you don’t have photos or copies down one floor is the business centre and they’ll do them there for you. You don’t need a TM30 filed for a short term extension there. 1,900 baht and you’ll probably be done in 20 minutes. Forgot to mention the extension is 30 days. Added on to your existing stamp so no downside to going early.
