H4 Canadian student with I-485 pending, admitted to university and got I-20.Best way to get I-94 on F1?Thanks

Question

This is a very complicated question. Please grant me your expert opinion. Thanks a lot.

Answer 1

It's true, you can only get an I-94 at a port of entry. You could exit the US, apply for a student visa, then re-enter, but then your I-485 processing would stop.
Or you could apply for a change of status from H-4 to F-1 while in the US, using form I-539.

Or you could wait for the I-485 to be processed and get your green card; then you won't need an I-94 or anything else.

Answer 2

I think there is something missing here... I-94 is issued to all non-immigrant visa holders at a port of entry....
