I pretty much face the fact that if I end up getting the tattoo I want, I will either have to wear long sleeves to all my job interviews and probably for the first several months of work, or get the same tat done on my leg/calf area where it would be covered by jeans or khakis every day.
I say first several months, because it is highly unlikely that I will have to worry about meeting with clients or customers in my chosen field - and if I do, it would be in a meeting environment where I would be prepared and would have warning enough to make sure I wore at least a long sleeve shirt that day.
But... let's face facts, folks... yes, tats are symbols of expression and what not... but no, they do not look professional in a business environment any more than a facial piercing or a mohawk would. The societal picture of a businessman just doesn't jive yet with our modern tendencies towards tattoos and other forms of expression... maybe they will eventually, but we've all been force fed the clean cut businessman in a suit or shirt and tie for way too long to reverse the trend so quickly. Give it time, and it might change... but for now, get used to it.
