If a 3-month non-immigrant visa in Thailand cannot be extended to a 12-month visa due to missing company documentation, would there be any issue with leaving the country briefly and re-entering with a visa exemption? Considering there is an existing work permit, how would this process affect the status of the work permit, especially since the required documentation may take 4-5 weeks to become available?
TLDR : Answer Summary
When leaving Thailand briefly to re-enter with a visa exemption, one cannot hold a work permit under that exemption, leading to its invalidation. It's advisable to apply for a new Non-B Visa instead of using a visa exemption. The required documentation for the work permit may take several weeks, necessitating a restart of the application process at a different embassy to avoid complications.
