Hi My last entry to US was April - 2012 but my Passport was expriing on March 2013 so i got i-94 stamped till march 2013 eventhough my visa is valid till Aug 2014. last week I got new renewed passport. I am just wondering what is the process to renew the I-94 card? does my employer need to file H1 again? or can i renew it in other way. Please adivse. Thanks
