485 pending, travel with EAD/AP

[yimanshi]

I have applied for I- 485 based on marriage. I've taken the interview but my case is pending due to priority date not being current. My PD is April 2010, and the current priority date is Feb 2010. I have plans to travel out of the country in October 2012. Is it safe to come back with EAD/AP combo card? If, however, my PD becomes current in Sep, how long would it take to get my GC? Please advise.

Thanks in advance.
