H1 to F1 to H1

[inkprs]

Hi,

I was in post Bachelor's degree F1/OPT status till October 2010.
My H1B started in October 2010.
I did change of status from H1B to F1 in May 2011.
I am currently in post Master's degree F1/OPT status as my OPT started in October 2012 and is valid till October 2013.
I want to go to H1B status now.

1. Can I file H1B right now? I mean in February 2013? Do I need to wait for the quota in April 2013?

2. Since I have already crossed 1 year 9 months since Change of Status from H1B to F1, don't I need to get into the lottery system in April 2013?

Thankx!
