My next border bounce is due on June 4.
I have Spouse/ Family Visa. Rather than doing another border run, I would like to apply for a yearly extension at my local immigration office. When is the latest date I can do that?
TLDR : Answer Summary
The latest date to apply for a yearly extension based on a Spouse/Family Visa in Thailand is the expiration date of your current visa stamp. However, it is recommended to apply earlier—ideally at least 30 days before your stamp expires—to ensure you have ample time to gather necessary documentation and address any potential issues.
