Wisconsin is rather strict on offenders, including those that are first time offenders 25 or older. If you have however committed an offense under the age of 25, at your offense was of a low enough classification, such as that carrying a maximum sentence of 6 years or less of imprisonment, you are eligible for expungement. However, the crime cannot be of a sex crime nature, nor felony of most classes. Typically, misdemeanors have the best chance at being expunged, while assault and felony charges, regardless of expungement eligibility, are often denied and appealed.
