PNP will show as eligible on your EE profile only when/if you get a nomination from a province dropped on your EE profile and accept it. So you need to track your eligibility for individual provincial nomination programs outside of EE. Usually provinces have their own portals/websites to accept your "nomination application" (which is different than your "permanent residency application") and they invite candidates to apply based on the criteria
@Naturgrl mentioned. See steps below:
1. Search for individual provincial nominee programs and see which ones you can qualify for as
@Naturgrl said.
2. Go back to your EE profile and make sure those provinces are selected as your provinces of interest. You can select multiple provinces, it doesn't diminish your chances of getting a provincial invitation.
3. You wait for a "notification of interest (NOI)" to drop into your EE message box stating that a province is interested in inviting you.
4. You go to that province's website again and read the instructions on how to apply. They usually ask your EE application number so they can inspect your EE profile and link your nomination certificate to your EE profile automatically if you're nominated. As you can see this application is outside of your EE profile.
5. You follow the province's instructions and hopefully get your nomination certificate. Shortly after you'll receive an automatic selection in your EE profile asking you to either accept or reject the nomination you received.
6. When you click "Accept", you'll now see that "Provincial Nominee Program" shows as "Eligible" on your EE profile. This means you may get invited by IRCC in the next Provincial Nominee Program draw if your CRS is higher than the cut off of that particular draw. You make your "permanent residency" application to IRCC under Express Entry.
