Can I apply for a re-entry permit a week before my extension of stay expires?

The discussion addresses whether it's possible to apply for a re-entry permit shortly before the expiration of a visa extension. Comments clarify that while it's theoretically possible to apply for a re-entry permit just before the expiration, it is crucial to return to Thailand before the visa expires. Some users note that if the visa has already been extended as a tourist visa, obtaining another extension could be denied, potentially leading to the need to leave Thailand immediately.
