Re-entering US from Canada when H1B extension petition is pending


I'm on H1B. My Visa and I-94 is getting expired on 15th Oct 2014.


I'm planning to apply for extension now. But I've a family wedding to attend in mid of August 2014 in Canada.


My question is that if I apply for extension now, will I be able to go to Canada and re-enter US when my petiotion for extension would be in pending state? Because in no case will I be able to get the status of the extension by mid of August 2014.


Seeking help in clearing this doubt.


Thanks in advance!
