Hello, I personally feel that tattoos especially the ones you've mentioned you have should not pose a problem. There hasn't been any source absolutely anywhere (at least that I'm aware of) that says tattoos will cause your application to be denied. If a person perhaps has ties with gangs and it shows through your tattoos, then perhaps maybe, it could pose as a problem in your biometric check. As long as you have a clean record I would not be worried about the tattoos that you say you have.
