Hi I want to do my 90 day reporting by post, can anyone tell me if I need post it one week or two weeks before the date?
TLDR : Answer Summary
To successfully complete your 90-day reporting by post in Thailand, it is recommended that you mail your report at least 14 days before the due date. While some individuals have reported success sending it later, it's important to check whether your specific immigration office accepts mail-in reports.
