I'm currently in the Stated in F1 category. My visa expired July 2008. My I-20 is still valid until November 2011. I'm in good standing. I'm also applying for residency (I-485, I-130) and my case is being processed. I am granted I-131. My question is, if I travel back to my home country over this break, when I return to the States early February 2010, do I have to go to the US Embassy to apply for another F1-visa? Thanks for your help.
