regarding work permit

if person got workpermit through one resturent but later, if he dont want to work in that resturant , is it possible to work any other hotel and for that what he has to do ? plz, i am waiting your quick response .

I don't know if this is just for American nationals, but from my understanding, your work visa is YOUR visa. No one can take it from you, no matter who gave it to you. I only suggest that if you quit you find another job right away. After a week of not being with a company you might start having problems. Good Luck, I'm in the same boat.

Possible, also grey area at times, however, when it comes to Visa renewal time, you will need a new sponsor and go through the process. And if your new job can't sponsor you, say goodbye to Japan.
