In Illinois, a (one) simple DUI is not normally a bar to grant of permanent resident status. However, you must tell the truth about such arrest and you ought to see an attorney to confirm that it is only a simple DUI. Additionally, marriage cases before USCIS are not that simple. At least, you should seek a consultation with an attorney to understand the broad parameters of the process.
My colleages are correct. Immigration law treats criminal adjudication differently than does criminal law. You should collect all information concerning the DUI and consult with an experienced immigration attorney who can provide you with a legal opinion of your options based on the totality of your immigration history.
