Can I extend my grace period beyond 7 days after canceling my Non-B visa and work permit in Thailand?

The user is inquiring about the possibility of receiving more than a 7-day grace period after canceling their Non-B visa and work permit, as their new employer requires 15-20 days to complete processing for a new work permit. Responses from the community suggest that extending the grace period beyond 7 days is unlikely, with recommendations to cancel the visa and opt for a 7-day extension available for a fee.
