Hi! when I first came into the US I came to Calif. State Univ. Now I have transferred to another school so I still have the CSU visa stamped on my passport which actually expired in May 2002. I am suppossed to go for a conference to Canada and I have a valid I-20 until 2006. My international students counsellor said that there would be no problem for me to enter back into the US as long as her signatures are there on my I-20. But I'm still not convinced since I-20 and I-94 are valid documents to stay within the country and a visa would be required to enter in the US. I leave for Canada on the 29th and I want to make sure whether it would be wise for me to leave the country. Kindly advise me if anyone has had similar experiences.
