There is nothing written on your passport that says 'this person was given a criminal record' on blah blah date
But I am guessing what you really mean is can anyone at the US customs gate know by looking at your passport whether or not you have a criminal record and therefore refuse you entry to the US? The answer is no, they cannot.
If you search this section (and the law section too) you will find many numerous posts on this very subject. Just tick the 'NO' box on the paperwork you are give on the plane that asks do you have a record
And tell your 'firns', what ever that is a shortened version of, to stop looking nervous.
