I have got an extension for my expired H1B VISA. However, now i have applied for my L1A processing.
Due to certain circumstances I need to shift the company on my approved H1B petition. so,

1) Can i do that while my L1A is getting processed. what happens to my L1A?
2) Can i do that when my L1A approved petition is received
3) When I go back to India for Stamping ( new company) can I get my wife's dependant visa also done.

Thanks in advance to the answerer.
