But it is strongly suggested that you bring your passport and other immigration related documents with you.
Make sure that your flight does NOT land/stop over at any other places other than 50 US states (even excluding US Virgin Islands) before you reach PR or you must go through the immigration line and deal with CBP. And almost 99% sure your entry will be declined. H1 visa holders can only go to Canada and Mexico but NOT any other countries or islands and come back without VALID visa (NOT any approval notice will get you in US).
