Can H1B extension be denied?

My H1B Visa is expired on 30th Sep 2015. I have filed my H1B extension in regular processing in USA, but its not yet get approved. In this case i need to travel to india on next week.

I know, If i m traveling to India,i cant come back. But i need to know about my visa extension. Will my H1B visa extension get approved? or any chance will H1B visa extension denied because of traveling outside USA?

Please help me on this.

Your H-1 extension will continue to be processed even after you leave US and will be approved/denied on its merit. The decision wont be impacted by your travel.
