Fortunately, you were able to have the DUI downgraded to a lesser offense. Certainly, a DUI conviction would have been a red flag. During the naturalization process, an official assigned to your case may ask questions concerning the incident. However, a conviction for minor traffic offenses should not stop your application for citizenship. That being stated, it is always helpful to directly consult with an immigration attorney.
Negligent Driving should not generally impair your ability to be a US Citizen. However, you should probably have an immigration attorney go over the paperwork. For example, you most certainly do not want to admit you are a "habitual drunkard," which is one of the odd questions there. Presumably you were found to have no significant problem with alcohol. The BAC level is low and did not result in license suspension.
One thing you could do is petition the court on June 30 for a "deferred sentence." This is essentially a temporary conviction, and it allows you to legitimately state that you do not have a conviction on your record. You were, technically, convicted, but the conviction was vacated. If you have questions about this feel free to contact our office for a consultation on this issue.
