Even a misdomeanor can exclude somebody rom getting federal aid.... But most of the time they won't check municipal courts and smaller charges. But it could bite you in the but later if they look into it. If you get a charge expunged its exactly that expunged, for financial aide sakes just don't admit to even being convicted of a crime. Not even a misdomeanor. It's there job to look into it. If charges get expunged i doubt he will have trouble in getting aide. I have a friend with a drug conviction in a municipal court and used a conditional discharge and has yet to have his charges expunged... He also gets full aid through FASFA.
