I just wanted to post this here as an FYI for those just starting their process. My husband and I applied for a study permit for me a month and a half back (because of the uncertainty with how long Ottawa would take, we didn't want to keep putting school off for me) before we got the PPR, and we just got the approval for it.
So, for those of you that this is an option for, it's certainly possible to get a study permit and go to school while you're waiting for your sponsorship application to go through. When I turned in my application for the permit this is what I included:
-The app itself
-The fees
-A statement of financial support from my husband
-One of his pay stubs (to show his income)
-My own statement of why I'm going to school and what roots I have in the states
-A lease that will continue while I'm in school (for roots in the states)
And that was it. Now, my lease is with a friend who will be storing my stuff for me while I'm gone. So I'm renting a space from her. When I wrote my letter, I just said that I was renting a place in the states, my stuff is there, my family is all in the states, and I kind of listed what jobs I could apply for in the US for "when I go back".
So just a good news story for anyone who might want to consider this route.
