I entered US after my consular process at chennai on 17th Feb 2002. SFO was my port of entry. I have not yet received my GC. But my wife, who also got her GC processed with me and entered US one month later (15th Mar) at the same port of entry, got her GC a week ago. Can there be an explaination to this? Or is this a hit-or-miss issue? Do I need to contact someone at CSC? Please help with your experiences. Thanks.
