As I mention before, I changed from F-1 to H-1 last year. I got my H-1 status in Feb 2004, but I went to my home country to get the H-1 visa stamp in August 2004. So I would like to know for counting my H-1 status, is it the date that USCIS (the Immigration) approved (which is Feb 1st), or the visa issued onto my passport (which is in August)?
