Thanks, indeed I contacted a lawyer and I am waiting for a consultation.
If I switch to visitor, can I restore to worker once I receive the AOR? Or the restoration process is only for when you don't renew your status in time (so if I would let my work permit expires and have no legal status). As far as I understand, you can't switch back from visitor, so the option to restore no longer is viable which means that I loose the possibility to apply for BOWP.
