It's kind of a silly question to ask, but I need to know

ok...this is kind of silly...to me. I was gonna get a tattoo on my back, But do you know if there are any rules against having visible tattoos in master's swimming? I know for high school swimming, I wasn't allowed to wear caps or speedos bearing another team logo other than my own team..so is it possible that they don't allow the tattoos? What about USA swimming? Are the rules the same? David
