Leaving Canada during visa extension process

[KelseyE]

hi,

My current study permit expires on August 31, and I would like to spend 2 weeks at home (in US) and return to Canada before my current visa has expired. I've applied for a study permit extension which would be effective September 1 if accepted. Will I be able to return to Canada mid July, and will my visa renewal application be affected by my 2 week absence from Canada?

Thanks!!
