I am aware of the link.
It is too broad and covers all DO across the country and we know how they differ in processing times.
If you try to narrow it by DO, then you have too few samples left , for it to have any statistical significance ( for example , if you look up Baltimore DO, you will see only one July applicant posted a timeline, the last before it being the ones who applied in May , and in TOTAL just ten applicants posted their timelines for the entire period of 2011).
To get an idea of current processing times I'd prefer to use the timelines posted in signatures or updates of members who frequent this or other public forums related to immigration. You get somewhat greater number of samples and little higher rate of accuracy.
Unfortunately, it seems like people who apply at Baltimore DO don't post much (there used to be 50+ page thread, which has not been updated in a long run and any attempts to revive threads about Baltimore DO timeline ended up with few or no updates by MD applicants).
So,for lack of better option, I am using the existing (may be already somewhat outdated) signatures and updates of Baltimore DO applicants here to get a clue what is and isn't normal pattern of processing times.
It seems like there is large parity and difference in when the IL are send and interviews scheduled.
Some posters I saw here reporting an interview scheduled only 2 months after NOA1, others don't get scheduled until 1 months after FP. still others don't get any updates in longer period of time.
Since Baltimore DO has same date Oath ceremony (though not all get to be sworn same day) , I would prefer not to be scheduled for the interview until after the 5 year mark, so I have no reason to wish for too quick update and interview date.
But it would be great of more posters shared their timelines, so we would know when to expect the changes in status and what is more general pattern of processing times as opposed to unusual delays.
Good luck to all!
