What if Bahrain CPR/visa got cancelled??

I am an Indian. working in Bahrain.  if my Company cancel my visa/CPR  without my knowledge. what can I do for stay in Bahrain and search for another job?

What can be circumstances of getting the extension???

Once cancelled, you have 30 days to leave or to change employer.  This can be extended by another 30 days by going to LMRA and asking for extension.  That is pretty much all you can do.

i have already extended my cancelled visa can i exit bahrain airport theres a receipt in my passport with the extension can i exit airport without my old sponsor approval

Yes.

thank you very much
