Complicated L1 extension issue .. help pls

[keshu_m]

My company applied for my L1B petition in 2007 which was approved and I got an L1 visa in Mar 2007 which was valid until Aug 2009. However I traveled to the U.S only in December 2008. Since my L1 visa was expiring by Aug I applied for a L1 extension in May 2009. This was rejected in August due to some confusion with the I-94. So I had to travel back to India in Aug 2009.

I then applied for a fresh L1 visa based on my company's L1 Blanket petition. I got this new L1 visa in Sep 2009 and returned back to the U.S. This new visa is valid until Sep 2011.

My question is can I apply for another L1 extension?

Will my visa duration or stay duration be considered when applying for another extension?
I have stayed in the U.S on L1 status only from Dec 2008 to Oct 2010 - less than 2 years - Am I not allowed 5 years?

Also I am not sure whether I have exhausted my quota of extensions. Will my case be considered as 2.5 years the first time and 2 years extension the second time?
Or will the Blanket visa be considered a fresh start allowing me another extension?

Also what will happen if I transfer to H1 at this point of time ... will my L1 stay duration or my L1 visa duration be considered when deciding the H1 visa validity?

Please help with some answers...

Only period spent inside the US is counted as used. I don't see any complication in your case. Your HR should give you the answers.
