Went to immigration for the covid extension in Chiang Mai today. Business as usual. About 35 people ahead of me in the queue and I was there about 90 minutes. Was given the “under consideration” as I have every other to time

Hi there.. question..after my previous employer cancel my work permit with the department of labor, I can get a letter or any proof from department of labor that my work permit is already cancelled? Can I get back my work permit book after cancellation so I can show it for new work permit application. I'm moving to another company in another place.. thanks...
