Hi Kadian,
I hope you're well.
Just today, FINALLY, I have been nominated by PEI. Been waiting a long time!
In terms of the eligibility, you just need to have worked in a skill level 0, A or B in the last 10 years. That's a compulsory requirement (from what I've been advised)
The 2nd part is you really need to sell yourself and why You want to move to PEI. This information you enter in your EOI form. They really look at this and try to determine whether you really do want to come to PEI or just use the province to get into Canada and then move to your preferred Province. This is what I think PEI and all Provinces look out for. You need to be serious about the province or they wont even look at you. Fortunately for me, my preferred province has always been PEI, simply for the fact I have a young family and PEI is an excellent province to raise young children.
That's my advice, hope it helps, and best of luck....
