answer:It depends on where you live, but the short answer is “not much”. In Oregon, for example, I found this: The Oregon State Health licensing office requires that individuals wishing to obtain a License as a piercing technician complete paperwork and pay a $35 fee. There is no practical evaluation or examination. There are 700 registered body-piercing technicians in Oregon Flipping burgers, or piercing nipples, not much difference, apparently. You want fries with that?
