My mom petitioned for me on April 2010. Now in the USCIS, it says that the processing time at the California center is 24.9 months. But the visa bulletin says that they are still processing cases in my category, from 2005 (I'm an unmarried daughter over 21 legally present in the U.S as an F-1 student). At first we got excited because we thought my case would be ready by the end of April, but now I realize that we might have been wrong and it might take 5 more years for me to even get approved! I don't understand then why the different types of information. What does it mean?
