Not strictly visa related, but can anyone confirm which Bangkok Immigration office is currently dealing with Certificates of Residence (not TM30s or 90 days)?
TLDR : Answer Summary
The Muang Thong Thani Immigration office (Section B) is currently handling Certificates of Residence in Bangkok. You must have filed at least one 90-day report to obtain one. The fee is 200 baht, and the certificate will be mailed to you in approximately 10 days.
