MasterPenguin79 I used this address: "Incase of The foreigners who reside in Bangkok, make the notification by registered mail at

90 Days Report Section Immigration Division 1 , Immigration Bureau, Chalermprakiat Government Complex B Building120 Moo 3 , Chaengwattana Rd., Soi 7, Toongsonghong, Laksi, Bangkok. "

MasterPenguin79 mailed it in by EMS. It's was the first time since reentering Thailand. I have to report to Division 1 (Government Complex). Submitted TM47, TM30, TDAC, and Passport picture page with visa last entry page. I included a return prepaid EMS envelope so I could track when and if they send it back. I was on pins and needles for those 5-6 weeks.

We mailed ours into Chaengwattana Immigration Division 1 for 1st time and got the approved 90 Day Report back in about 5 or 6 weeks.
