Update:

Just got new work permit today but didn't get visa due to one missing document.

Current visa expires on 6th. The officer said I can still come back until Sept 26 without going out of the country.... Still feeling worried 😥

Has anyone successfully got it in a situation similar to this?

Hi all,

I need some help/advice with visa/work permit for job transfer.

My work permit is scheduled via BOI system to be cancelled on Monday (31st August 2020). They said I can stay only until 6th September 2020. On Monday, I'm going to cancel my current visa, get 7 days extension and apply new work permit. New company is not under BOI.

What happens if my work permit application doesn't get approved within 7 days of extension?

Do I still need to leave the country in order to re-apply work permit?

Or I can re-apply work permit while holding an automatic amnesty visa?
