@Penelope *******
, your work permit doesn't make you report every 90 days :/ It only allows you to work here IF you are on the correct visa/extension
However because you do 90 day reporting I can say with near 100% certainty you are not on ANY visa anymore and instead on a yearly extension of stay.
I'll try one more time to let you kow what you do.
Go cancel your work permit, take that receipt and the termination paperwork from your company to the immigration office and cancel your extension of stay, THEN leave the country.
You seem to think that letting your work permit and/or extension expire will cancel them, I can assure you it does NOT.
If you're ever gonna work in this country again (like EVER) you need to cancel both of them the proper way.
Good Luck, (y)
