Regarding H1 petition awaiting approval / can I go to India in the meanwhile ?


		Currently I am on H4 visa and it is valid till September 1st, 2014. My husband got his H1B and my H4 extension approved for next 3 years (valid till Aug, 2017).
		I applied for H1B this year and my application has been picked up in the lottery and I am awaiting H1B petition approval.
		I am planning to go to India in August for 3 weeks. I would want to go to India once my H1 is approved.
		Please let me know the obligations (if any) for my trip to India. 
		Any advice is much appreciated.
		Thank you.
