What state do you live in? The laws are different for everyone...is it a right to work state?
I live in the Chicago land area and all I have is a GL and a business lic.# registered with the state.
It different in Cali ... I know for a fact. Other states I'm not sure of....Somebody said if your a Packers fans all you need is 5 or more teeth and you can work.
I read that some where, or maybe I wrote it down and then read it some where:)
