- Yes, you can search for jobs in B1
Before answering other 2 questions, H1 cap is over for 2012-12 FY, so u cannot start working until October 2013 if at all you find a “Y” employer and they file H1 with COS (Change of Status) from B1 to H1 and approval comes…
Your “Y” can only file H1 only starting April 2013.
So, what you are trying now is impossible.
2a. Employers can do change of status from B1 to H1 for which you dont need stamping unless you come out of US.
2b. If Y applies H1 without change of status, then after your H1 petition from Y gets approved, you need to get Visa stamped. Visa stamping should mostly for 1st timers to be done from home country exception of Masters students from US in Canda or nearby US countries.
- Problems can raise in many ways if there is an illegal status found in your previous US or any overseas stays.
My Advise : Dont stay in B1 for a long time thinking you can switch to a US employer, you may screw it. stay for a short while now and come back to India, if you get another chance to visit US during May or Apri2013l, start hunting for jobs,thats the right time for whatever questions you posted…
