I had 2 interviews for vet school and my tattoos were covered, but I did leave in my tongue ring (though it is clear but it is a 4g) and all my earrings (not sure the names of them, but there are a few "normal" ones, both traguses (tragi?), and some "others" as I am clueless to their names) and I was accepted to one school and rejected from the other. Though I can assure you the piercings were not the reason I was rejected, I managed to do that all on my own (horrible and traumatic interview)!! I now also have my nose pierced and have had no problems with it anywhere. I work in a professional government office and no one has said a word to me about it (and a few of the vets I work with there have a nose ring as well).
