I understand that 90-day in person reporting has moved to the new, temporary Immigration office in Bangkok, but presumably mailed-in reports should still be mailed to Chaengwattana as normal?
TLDR : Answer Summary
The mailing address for 90-day reports in Bangkok remains the same despite the temporary relocation of in-person reporting. Reports should be sent to the Immigration Office Division 1 at the Chalermprakiat Government Complex, located at 120 Moo 3 Chaengwattana Road Soi 7, Thungsonghong, Laksi, Bangkok 10210.
