It certainly takes a while. Yo must be patient, because is not custom that records are produced the same day  they are requested. The standard time frame is at least 20 business days after receiving written acknowledgement from the FOIL office.
Did you provided a phone number along your request?
No, i didn't do that.
My FOIL request has been rejected, can i file a appeal?
That rejection has been for a whole or only for a part of your request?
It was for a part on the information requested, yes.
You may indeed appeal the rejection then. You must proceed writing before 30 days from the date of denial for your FOIL request. It must contain a description of the contents which were rejected and have your appeal identified with the date of your record request.
Thank for the answer. Last question, please. what can i expect to happens when my requested records are ready to inspection?
