Eligibility and points. Most folks may be 40+ in age. Keeping the strange 75 score aside, the only way to apply for most is Paper method. Please note that not all PNP give 600 points in EE. Only EE aligned PNP programs give 600 points. Eg: OINP Foreign job offer stream is a paper PR only nomination. It wont give any points in EE.
Another advantage of Paper PR is folks with NOC C and D can also apply.
Another interesting advantage of Paper PR is it does not require IELTS (NOC 0, A, B), does not require any education evaluation, no need of proof of funds, no need to even be inside Canada.
Biggest disadvantage is that IRCC treats us like rotten junk. We are neglected always and the files move super duper slowly. But usually in the end, since the requirements are very low, PR is virtually guaranteed if the background and medicals are clean.
