The PGWP is a work permit that allows international students to work in Canada after they finish their studies. How long the permit lasts depends on how long the study program was, up to three years. To get it, you must graduate from a Designated Learning Institution (DLI) and apply within 180 days of getting your final transcript. Work done under the PGWP can help you qualify for permanent residency through programs like Express Entry and Provincial Nominee Programs (PNPs).
