I got H1b visa stamped on March 2012 and extended till Dec 2012. Again my employer extended my petition from 2013 Jan to 2013 Dec, extended petition from 2014 Jan to 2014 Dec, again got a petition extended from 2015 Jan to 2015 Dec. My last stamping was done on 2014 March. I worked in the USA until November 2014 only. After that I return back India and Mexico but I travel to USA for B1/B2 frequently from 2015 to 2018 July. Can I do an H1B cap exempt now?
