I'm currently working on H1B which is valid until Mar 2009. My H1 stamp in the passport has expired Mar 2008. My 140 is approved. I currently have a I485 pending whose priority date will be current in the month of August. I have not applied for Advance Parole.

I'm planning to go out of the country and get my H1 stamped get married and bring my spouse over H4 visa.

1. What happens if my GC is approved before my H1 Visa stamp? Will I be to re enter into US Or Is it considered abandonment? What would be my status?
2. How can I bring my spouse if I marry and my GC gets approved?
3. Is it possible to bring my wife if I’m married and my spouse has H4 stamp and my spouse is not in US before GC Approval?
4. Do I have to inform USCIS about my travel plan?
