Can I travel to India and return back without my H1B visa extension stamped as my amendment is in progress ?

My visa extension is approved recently on Dec 10 2016 and i got extension approved till Sep-2019 , but my office location is going to change from Westlake-Tx to Irving-Tx. So my employer has filed a amendment for the same, is it possible for me to travel to india and return back now as my extended visa stamping is not yet done ?
