I was arrested about 6 months ago and was fingerprinted and booked. Fortunately, when I showed up for my 1st court date, the D.A. advised me that the case/charges had been dismissed. BUT they did say that there was a one-year time frame during which the case could be opened up again. I've called the since, to make sure that I don't have a criminal record for this, and they assured me that since there was no conviction, it shouldn't show up in a background check...
Now, I have to do FBI fingerprinting for a potential employer. It is for a credit union, and I know they have strict rules. Will this arrest show up on my FBI fingerprinting results? And how long do the results normally take to return?

And one last question - do infraction convictions (non-traffic) also show up on the FBI fingerprinting even if you were never fingerprinted or booked for the arrest?
