Amendment rejected, can i travel to india and come back to us


I am in US. I filed H1B Amendment request while i was in India, it went to RFE and got rejected now. My original Petition is still valid till 2019
Amendment was raised just for Job Role Change. Client and Location is same for Original petition and Amendment petition.
Please Advice if i can travel to India and come back to US as my Original petition is still Valid.

Yet to get the denial letter from USCIS, currently I don’t have any client or employer letter to work as per role in original petition
