H1B petition approved, can i go for L1 now

Hi,

In June 2012 i applied for H1B and in October 29th the H1b petition is approved.

Now my company want to do L1 for me and send US for 1 year, but they dont know about my H1B petition.

Please let me know if i go for L1, what are the issues may come?

Is My H1B petition will cancel?

Is company will come to know about my H1B petition?

If i go for L1 interview is there any chance of asking questions about H1b petition?

Please let me know what other problem may i face in this situation?

Thank You,

Manu…
