Cancellation Letter: My contract in the current company will end in June so as my Work Permit.

My contract in the current company will end in June so as my Work Permit. Now, I am wondering if my work permit expires, can I automatically get my Cancellation Letter from the Exit-Entry bureau without my employer applying for cancellation online or in the office? Or does she still need to apply for the cancellation even though my work permit already expires?

My residence certificate is still valid until July though. I just need to make sure that the cancellation letter will be given to me whether I leave the country or move to a new company.
