Rest of 2010 filers,
If CO is not yet decided with the March movement and waiting for the USCIS signal regarding ballpark total of filers, then there will be a good forward movement considering the fact that many of us are not going to file in the first week.
Several of our friends received mail from their attorneys ( including ourselves) not to rush them . ( I could see 2008 PDers around us are still filling their forms, waiting for affidavits ... )
Hope for the best !
