I94 expired and Filed H1B extention petition and need to go back to India

My H1B Extention petition is filed on 09-August-2013 and my existing I-94 got expired last week ( to be precise 24-Oct-2013) and now I am planning to go back to India on November 15th due to some personal issues.

Since my extention petition is still in review stage please let us know what could be the potential problems if I travel to India now.

Whether my extention petition will be stopped at any stage if I am in India and what is the process if the petition goes into RFE at any stage during my stay in India.

Please help me in this issue.

Thanks in advance.
