The process is supposed to take no more than 30 days, but do to prevailing anti 2nd amendment attitudes and sentiments held by most law enforcement agencies, it can take, in some cases, upwards of a year to be issued one; other localities, more accepting of the second amendment will issue within 30 days. In addition, there are multiple cases of denial for "arbitrary" and vague reasons, often termed as "public health and safety".
Oh, you want to apply for a FID. Here sign this mental health waiver and we'll hopefully issue your card in the next year or so.
LEO- Let me see your FID.
Law abiding citizen-Sir, respectfully, I do not need a FID since I am in possession under one of the exemptions provided for by NJ law.
LEO-Get the fuck out of the car and get on the ground!!!!! You cannot possess a firearm without a FID!!!!!
