Hi, there I am very new here, and I am very glad to find this website, please help us out. My wife came here on a K3 visa 8 months ago, in the begining we did not file for AOS, since we have paid all fee for I-130, and it has been sent to GUZ few months after she got here and we had our 2nd anniversary already, so we were thinking it might be quicker just go back to China to do the interview and get it all done by then. But for some reasons which we do not know, we were in the name check black hole, do not know when we can get our P4. So we are thinking to file for AOS now, also better beofore the medical examination expires(only good for 1 year). But our question is if we do file AOS, what would happen to our I -130, should we contact someone or write somewhere, or it would automaticly be canceled? My other question is , when I was reading the I-485 form instruction, it says "you may file I-1485 at any time after the principal applicant is approved,if a visa number is available", when does it mean "a visa number is available"?--is the time GUZ send out P4 or what? Should we still wait, or should we file AOS? Advices are very much needed, thanks a lot. Jim/Li
