Complicated L1B to H1B situation

[hiralsharma44]

Hello All,

I need help urgently with my situation.

My Situation:

1. I came to USA in Sep-2009 for Company "A" on L1B

2. My L1B Visa and I-94 will expire on 21-Apr-2012

3. I have submitted Documents and company "A" will file for L1B extension in Apr-2012 first week

3. Mean while Employer "B" has offered to file H1B (New) for me on 02-Apr-2012

My Questions:

1. What information will I need to get from Employer "A" as proof of L1B extension processing application?

2. Will there be any conflict if both "A" and "B" file for two different Visa types for one person during same week?

3. Do I need to travel to my home country to get stamping done if by 01-Oct-2012 my L1B extension is still not approved and my H1B (New) gets approved?

4. Or irrespective of status of my L1B extension, can I simply change status on 01-Oct-2012 and get new I-94 for H1 B Visa and start working for employer "B"?

5. If 4 is True - What if my L1B extension approval comes after I join Employer "B" on H1B?

I would be grateful if some one can help/guide me with my situation.

Regards,

Hiral
