my question is right now up to sept 2004, they are processing cases till Nov 16, 1999, but how come on their schedule, they adjust applications from 6/10/98 to 11/16/99 first and then go back to adjust 2/2/1999 to 9/14/1999???? r they doing faster than the schedule?

So after SEPT/30/ 2004, are they gonna adjust application that were submitted after Nov 16/1999 or gonna go back to to do SEPT/1999 to Mar 2000 as their schedule???

And one more thing......they will adjust applications in the period of 5 months each time right?? so my I-485 ND is 10/14/2000, is that gonna be processed in 2006 as thier schdule?

i am sorry again if this has been discussed, and hope u guys can give me some answers
thx!
