Do I Have to Fill Out An Application and Get Hired Before I Get My Working Papers?

I am getting a summer job so I don't have to constantly hassle my mom for money, and I want to work at Chick-Fil-A (A place that hires kids my age) and I was wondering, do I have to get hired bee\fore I get my working papers? P.S I Live in Philadelphia Pennsylvania, trying to get hired in Plymouth Pennsylvania.
