Hi AJ,
I know everyone can apply to PEI without job offer or having relatives there. i just tried to say that chances are less and that i can say from the previous nominations which PEI issued. and also on the PEI official website, they have mentioned that "
Priority will be given to applicants that are living and working in PEI."
Of course, it costs not a single penny to submit expression of interest, i think candidates with low CRS score including me ( mine is 351

) , should try luck with the PEI.
