Not legal advice. These are counts of applications that USCIS received and decided at each office, not the outcome of any one case or a prediction of one: a pending count says how many applications are waiting, not how long yours will wait or where it will be decided. Questions about an immigration case are for a licensed immigration attorney or an accredited representative.
