Hi!
I’m not sure how to apply OWP separately ‘cause we applied together. I patterned her documents in the same way as how I did mine; except that instead of an SOP, she’d written a Letter or Intent— stating her purpose of coming to Canada with me. We’ve also attached a copy of the acceptance letter from my Uni as proof that I have been accepted to my program. That way, it should solidify her intentions of being my support system while in Canada.
Hope this helps.
