Per my response earlier, I'm taking care of a family member, so I'm not home, my mom has been getting my mail. Anyways, she called and said I got a letter today and it felt like a license was in it (She didn't open it). So it's been about two or three days past 2 months. I turned in my info and fees May 6, so it took 54 days.
To clarify an earlier response, Oakland county does not have it mandatory to see the gunboard, unless something comes up in your backround check they want to question you on.
