Need your help!

I came here on a B1/B2 visa but I have recently applied (Oct 25, 2007) for I-485, I-130 and I-765 based on my marriage to my boyfriend who's a US citizen. I've heard that it takes 6-8 mos before USCIS processes my application. In the meantime I was admitted as a volunteer intern (not a form of employment) in a foreign diplomatic organization wc requires nonimmigrant A-2 visa for non-citizens. The internship is from Jan - May 2008, and my B1/B2 visa is only valid until Dec 2007. Do I need to apply for an A-2 visa even if the internship is not necessarily a form of employment? If so, what is the effect of this on my Immigrant visa application? which immigration laws are relevant to my case?

Neither, you are in the country adjusting status. If you want to travel out and back into the USA you will need to file for AP (I-131). The I-765 will get you employment authorization.

thanks for the insight. I did apply for EAD. But the internship is voluntary, not a form of employment. and it's gna be here in US too.
