Licensing is accountability. In this country you are held accountable for the services you render to the public. In this particular instance would you rather have someone with a license digging the dead skin off your feet or someone who grew up in a third world country that desperately needs work,any work to stay alive.These folks use chemicals, grinders, and sharp instruments on our bodies.If you want to work in this country get a license and maintain it. This is what separates the licensed anyone from the jack of all,master of none.
