  My I94 card along with H1B Visa expired at the end of March 02 but applied for H1B extension starting of Jan 02 and got letter from INS in 3 days after sending them my H1 Ext application saying they recieved my H1 ext Petition and will process my case. So can i stay back in country with no problem
