I hold a 3 years H1B on Oct 1, 2012. I want to take a break in 2014 for more than 3 months from work. I wil be on H4 for that period since my spouse haolds H1B status. After my break if I rejoin my office and resume work, will have to apply for H1B. Will I have to wait till the next slot or can my employer request for the transfer from H4 to H1B for the remaining unsued period of H4.? Please advise
