Take a week off, please make up an excuse.

Go home and get a certificate or something. If you can't take a long vacation, you can take a detour. Ask if you can take a few days off first, and then you really can't come back when the time is running out. Of course, there must be a transition before, such as how troublesome it is to apply for a permit. Send a message, make a proof or something

Or ask for half a month and then bargain with the boss.

Excuses are not important, but tactical issues are important.

I wish you success!
