It is time to renew my H-1b visa. The international office people in my university told me that I can renew for only 1 year because I started my H-1b in 2001 and it will be 6 years at the beginning of 2007. I remember I read somewhere that if I-140 is approved and I-485 is pending, one can renew H-1b for up to 3 years. Can anyone give me a link for the offical document or memo so that I can show it to the staff in international office? Thanks for your help.
