Right now I am in India. If i am not wrong you mean - I can still apply for NS PNP and there is no impact on CSQ.That’s a recipe for refusal. If you want to consider the express entry option, would be best if you move to that province first and surrender your csq. That way you will be able to convince the officer about your intention of leaving Quebec.
If my NS PNP approves then I can apply for Express entry and get the PR. and Once I landed in NS then I have to surrender CSQ.
