only on one condition you will get 3 yr PGWP if your both back to back PG course of having 1 Year each (3 semester) not of 2 Semesters, because according to Canadian standard , full time 1 year study consist of 3 semester.
so 1 yr (3 semester ) + 1 yr (3 semester) will give you 3 yr PGWP.
but for instance if any of the course among back to back is 1 yr (2 semester) 90% chances are you will not get 3 yr PGWP.
rest depends on VO.
tc..
there is no difference between 2 Year Masters and 2 Years diploma course.. suppose someone has done 2 years Masters he/she will not gonna get special treat when comes to PGWP..
lots of factors to considered when issuing PGWP like.
1. Total credits earned in course,, does not matter its Masters/ 2 Year Diploma
2. total contact hours the applicants gained.. (VO will check this with official Transcripts provided by the college)
3. your final grades and attendance credentials
i am telling you all these from Canadian education standard point of view.
if you are interested for 2 one year back to back diplomas// certificate programs , cross check the following:
1. total no. of Semester in single year, if its 3 semester then no problem.
2. total Diploma/ certificate credits.
3. contact hours per week.
