Last year I got the L1B visa to be able to work in US for specific projects while I was based in Canada. At the beginning of 2012, I was transferred by the same company to France for another project where I am still living.
The annual cap for the H-1B visa category has been reached for Federal Fiscal Year 2013 (beginning October 2012). As such, an H-1B visa will not likely be available to you until October 2013. The L-1 is most likely the most favorable visa category available to you and your company at this time. I suggest that your company consult with competent counsel to assess other options that may be available as well.
The earliest your employer would be able to file for an H-1B is April 1, 2013 and the earliest that you could be on H-1B is October 1, 2013.
