Arjun, I just went out of the country on AP after my interview. Same thing with me- wrote 'pending' in passport. My lawyer told me, if GC gets approved while I'm out, it's not the end of the world, but it will make things a bit messy. I believe you'd have to go to the US embassy in whichever country you're visiting, etc.
But, I took the risk anyway- I figured, there's no way I'm getting approved within one month of my interview- when most others have been waiting forever. There's no way I could get that lucky. Of course, i was right
Coming back in was no problem at all- a breeze.
I know others who are planning on travelling too- and I guess it really depends if you want to or not. I, for one, cannot stay stuck in one place for too long- due to work and a constant craving to travel- so I would always take the risk. I'm going out again in a cpl of months. I'm not going to put my life on hold for this thing to come through- it will, when it will- and hopefully it will be while I'm in the US.
Jdawg, yes, I will ask for an inquiry. My lawyer himself had said right after interview that he'll do so, after waiting one month- so perhaps he has already. Just haven't had the time to get in touch with him yet. Maybe tomorrow.
