After I graduated from my first master program, I worked in the US first using OPT then under H1B visa for 2 years. Then I resigned from the job to attend an MBA program. I know I will not have OPT after graduating from MBA program, but can I be exempt from the H1B visa cap and do not need to go through the lottery process, given the fact that I used to have the H1b? In other words, can I work immediately after my employer's filing my H1b petition? I will graduate in August 2014, if I find a job right after graduation, can I work immediately without waiting for my visa approval, given the fact that I do not have the opt bridging the gap. Thanks for any answers.My first day of H1B is in Jan 2011. I changed my status from H1b to F1 at August 2013 for my second master degree study, and will graduate from the second master degree in August 2014. Do I need to apply a fresh h1 (under the quota limit) or can I utilize the previous H1 started from Jan 2011?
