In Miami, Florida, USA, the policy regarding minors and tattoos is subject to state regulations. As of my last knowledge update in January 2022, Florida law requires individuals under the age of 18 to obtain the parental or legal guardian consent form from Florida Department of Health filled in and have the present the legal guardian at the day of your appointment. It's essential for both tattoo artists and individuals under 18 to be aware of and adhere to these regulations to ensure a legal and responsible tattooing process.

Please note that local regulations may change, and it's advisable to check with local authorities or tattoo studios in Miami for the most up-to-date information on minors' tattoo policies.
