If you are a LPR, it is currently taking about 2.5 years for a visa priority date to become current for this family-based preference category, as they are currently processing August 2010 petitions. Even if the I-130 is soon adjudicated by the USCIS, the Consulate will not be able to schedule an interview until a visa number is available.
