She got nomination already. With RRS (job offer) applicant can request for wp support from AAIP to apply for wp while the PR application is going onI now understand, it is not a PNP nomination, but WP support letter, she can only apply for WP first, after she gets the WP working several months (possibly 3-6months) she can then apply for the Alberta AINP Alberta Opportunity Stream (AOS), after approval of that, then PR application.
Furthermore, her cousin is just the ceo and a lot of people fall in same category, as far she can prove her experience and meets all the requirements of the WP application, there would not be an issue.
