I am in a state of dilemma as I recently got laid off from my job on 30th december 2011 and have been on bench since then. My husband's I-485 priority date is approaching soon in Aug 2010 and Green Card date is currently on Jan 2010. I wanted to know that shall I file for I-539 (H4 dependent visa) now since I am not working from last 12 days and when we file for I-485 AOS we can show them pay stubs for month of december that I worked. My other question is that can we file for I-485 while I-539 application is pending. Does USCIS wait for I-539 to be approved before it grants EAD? I have read several blogs and found that H1 to H4 COS can take upto 7 months so do u advice to go back to my home country and then get H4 stamped for faster approval or can I file for H4 COS in USA itself and simultaneously apply for I-485 once GC priority date is current?
Thanks in advance for your guidance.
