H1 B Process in 2013 how long it takes ?

Hi,

My Stem Opt expires on 14Nov, 2012 . My current employer does not want to sponser me.I will be changing on H4 this year So for the next year in 2013 If any employer wants to me sponser When should I get the job and when I can apply h1 or When I can start work?

it will be diffcult to apply from H4 ?

I am graduate and have three year expeience.

You should get a job offer (who could sponsor your H1B) before April 2013 and get your H1B petition filed as early as possible. This time the cap got finished in less than 2.5 months and I believe it will be even less next year.

You can start working from 1st October 2013 if your petition is approved.
