My L1-B and I-94 is going to expire on 13th Sep 2013. My wife (does not works) and kid are on L2. My Current Employer will assist me to get our (mine, wife's and kid's) I-94 (of L1-B) get extended; but they (current employer) will do this not before June-July 2013. New Employer (Y) is going to file H1 B w/COS on 1st April 2013. [b]Questions:[/b] New Employer files H1 B w/COS, tentatively by which month will I come to know about status (approval / REF)? While the H1-B w/COS is in process / progress, can I get my I-94 extended in June-July timeframe? If Yes, then, will the extended / new I-94 (of L1-B) impact my H1-B processing? If the H1-B w/COS is approved, then, will my current employer come to know about it (assuming I do not notify)? If the H1-B w/COS is approved, then, will I get a new I-94? If yes, when and of how many months/years? And, would I be able to continue with Current Employer (on L1-B), from Sep 13th 2013 till Oct 1st 2013 (note that my I-94 of L1-B is expiring on 13th Sep and I am going get an extended I-94 on L1B in July 2013)? If everything goes well, i.e, I get H1B and am still working on L1B till 1st Oct, then can I continue working on L1-B for few more months, before joining, new employer with H1-B/COS? Please help me to get these queries answered.
