I didn't order, Just sent an email. It's different.
Does anyone know if I get an OWP and go to another job within community, will they still process my PR or it is mandatory to stay working for the same employer?
You have to work for the same employer until you get your PR. At last minute, they may, or may not, ask for paystubs just to make sure you are still working for the same employer. If you change employer, you have to let them know and I think it might delay your application.
