H1B Work duration and extension criteria


I worked in the US last year, 2011 in L1 visa. I came back to India in January 2012 since my L1 visa was expired. I got my H1 visa now for 3 years.

Question is, if I travel to the US again in H1B in 2012(that is before Dec 301st), can I extend my H1b Visa after 3 years or the extension is not possible because my L1 visit will also be considered. Some say so but i am not sure how this works.

Can somebody explain me how this works.

your total stay out of US needs to be 365 days or greater in order to reset the clock, otherwise your L1 time will also be counted in the 6 year timeframe. Do not worry you have lots of time to think about this.
