My parents applied to immigrate to Canada from July 20 10, which is a provincial nomination plan. The file number has not been obtained. Now it has been admitted to a university in Canada.

You can apply at the same time. Your province nominates investment immigrants, and you study in Canada alone. After you hand in your visa, you will get the visa result soon. You can log in with a study visa first, and then wait for the investment immigrants who apply at home (the cycle is about 27 months) to sign.

If you submit an investment immigrant visa for your family, you don't need to fill in the FN file number. It doesn't matter.
