Huh. This is interesting.
I have a nose stud. I love it. Not a problem for work (I don't work for companies that are that anal).
They are common enough here that most people don't even blink an eye. I always wanted one.
If you are serious, why not check out a good piercing shop and ask questions? They will tell you everything you need to know. Complications are rare, but can happen. You must be healthy and take care of it.
