family sponsored visa means your husband got his green card / citizen before
your marriage and you apply in Family-Based category, which has a different
priority date (check visa bulletin to see the two tables).
I believe you are a derivitative of your husband's employment based visa (EB
), The instruction says if you file for visa through 140 (which is for EB),
then submit to Phoenix or Dallas. Read again, it is in category 3E.
