Hi,
Yeah.. in Sask. province, as per recent change int heir rule, you will need to work min. 12months/ 1920 hours in any job, before applying for PNP. Also remember.. you may go there...and even if you get the job immediately...and work for 12 months..still the PNP nomination will take atleast 3-4 months (will take much longer in future with more number of applications). So, say on average.. even if you get a job in 1 month, work for 12 months and then wait 3-4 months for PNP nomination to come..you will still need minimum 17 months . So, anyhow your 12 months/1year PGWP will not be enough.
Once your 12 months PGWP runs out, you will then have to apply for LMO and receive a positive report to stay on and get visa extension, so as to continue working and apply for Sask. PNP. But, the main problem is... if your job is unskilled, or not in demand (as per Federal govt or how they see it), getting positive LMO is difficult and TOTALLY IMPOSSIBLE WITH UNSKILLED JOB (NOC C, D). So...if you don't get a positive LMO report, you will have to leave Canada. Considering this situation, ONLY go ahead..if you are sure, you are getting a skilled job which is in demand (so to be sure to get a positive LMO in future). Or else, opt for another 1 year full time course, complete it.. and then apply for PGWP , which you will get for upto 3 years...and then move to Sask. You won't have any worries of PGWP running out.
This recent rule change in Sask. PNP is a big blow for all those who dreamed about getting a PR quickly via Sask. student PNP stream, after 1 year of study. Now, to be sure..to make it through Sask. PNP, one will need to do a 2 years course (if they are studying outside Sask. province).
Best of Luck.
