Can I cancel my NON-B visa and receive 7 days grace after my employment was terminated?

The visa holder inquired about the process to cancel a NON-B E-visa issued outside Thailand after their employment was terminated. Responses from the community clarified that cancellation is not necessary as the visa can remain valid until expiration. Additionally, they clarified that specific requirements, such as a work permit and a letter from the employer, do not apply in this case since the person has not started working. The general consensus was that the holder could let the visa expire and leave the country when ready, as there are no obligatory grace periods beyond the typical stay allowance.
