Hi Folks, I have a stamped unused H1B Visa from my previous Employer. It is understood that H1B Visa is valid for a CAP Exempt Transfer for 6 years from the issued date. Would like to know which is the last eligible date (6 years from Reciept date or Notice Date ? or stamp date ?) for CAP Exepmt transfer in my Case. Below are the dates from my i797B and Passport Visa Stamping. I am based out of Canada. i797B: Reciept Date :April 20, 2012 Notice Date :January 10, 2013 Visa Stamping : Issue Date: 28 Feb 2013 Expiration Date: 19 Sep 2015 Any Response on this is much appreciated!
