Sometime ago my father, a US citizen applied for my brothers to migrate to the US (They live in Argentina). This was done in California and our priority date is Aug. 14, 2000. I saw your section on processing dates but wasn\'t sure how to calculate their waiting time. Both of my brothers are over 21 years of age, one is single, the other is married. Could you assist me and let me know if there\'s a way of expediting their applications? Thanks much.
