If one goes for a one year study program and then receives one year of post study work visa, is it possible to extend it for some more time? If so, what would be the conditions or requirements for such an extension?
A PGWP cannot be extended so either you have to find an employer to sponsor an LMIA with a job offer or apply for PR.
Generally recommended to go for a 2 year course to get a 3 year PGWp given with only one year often no way to actually get one year Canadian work experience to use for a PR application given if nothing else actually finding a job may always be a challenge
