re: tattoos
Kabuli,
I just read your post, and from what I know, its not about how many tattoos you have or markings, its whether or not they are visible when in uniform.
I have a tattoo on my lower back, and they knew about this from the 1st interview day. It didnt pose as a problem as it cannot be seen when im in uniform.
So rather than get it removed, see if it can be seen through a white shirt...although cc can wear a white vest top under shirts! so im aware of anyway.
Hope this helps (i didnt read all the other replies, so not sure if someone already told you)
