Hi,
if you have pro nomination under masters category you will not receive a work permit support letter. The PNP maintains that the letter is only for people applying for pnp under skilled worker, bachelors or experience class applicants.
If you send an application for work permit to CIC, to extend a PGWP with an employment letter and a copy of your PNP certificate they will still refuse the application because they need the work permit support letter, which PNP will not give to a Masters stream applicant. PNP maintains that the individual should get his/her own LMO for the same.( I meant the company you are working with will help you get it).
The PGWP cannot be extended, cannot be renewed and can only be acquired once, even if you did 21 degrees.
In case your work permit is about to expire and your employer is no mood to get you a LMO and you are a PNP who has filed for PR a good option would be to apply for a visitor/student permit again and sit & enjoy.
A good piece of advice in such a condition would be to not work beyond valid work permit in any case because that will jeopardise your application for anything and everything.
lemme know if any clarification required.
