I had change of visa status from F1 visa to H1B visa, which it got approved in Sep 2008 for duration of 3 years (until Oct 2011) through petitioner X company,
Due to certain reasons, I tried for transferring my H1B visa to Y company in June 2010 but due to lack of client letter it got denied, during the transfer process was going on, I was still working with X company.
Later I have transferred my H1b visa to Z company, during Nov 2010 which I got approved for duration of 3 years (until Oct 2013),from then I started working for Z company, Now as I have been offered with full time position from A company and I am willing to transfer my H1B visa, if this works fine then as soon as my H1b Visa from A company get approved I want to start work for it.
Now my question is, still now I didnt go for H1B visa Stamping to India, if I go with H1b Approval of A company, will it cause any issue because of changes of employer. If not after changee of employer when is it good time to visit India for
