Will DUI prevent from getting naturalized?

Minor mistakes like driving under influence of alcohol(DUI) can put you into trouble depending on the damage caused if any or if it was reason for your imprisonment. During the process of applying for US citizenship you shouldn't hide the truth at any of the various stages. If your explanation convinces the Immigration officer then all should be fine. Extreme cases its better to avoid applying for US citizenship five years since the date of conviction. Once your case is cleared its better to apply. During the 5 years as a green card holder prior to naturalization maintaining good moral character is a must.
