old and Expired petition reuse

[hilium]

Please bear with me for the long post.

[1]

I had an approved H1b petition through Company A valid from 2001-2004.

In 2003 i worked in US on this petition for 6 months and exited US in 2003 itself. This petition expired in 2004.

[2]

In March 2005 i re-entered US through Company A again BUT on L1.

[3]

In April 2007 , while i was in US , Company B filed for H1b counted in the CAP and got approved, I shifted to H1b status from Oct 1st 2007.

[4]

I transfered my H1 to Company C in May, 2010, and exited US on March 2011. The H1 petition through C expired in April 2011.

My Queries:

In April, 2013 :

-can I use the H1 in [1] to re-enter US ? If Yes, how much validity will it have ?

-can I use the H1 in [4] to re-enter US ? If Yes, how much validity will it have ?

Thank &Best Regards
