For naturalization, you have to show "good moral character" in the 10 years immediately preceding the application. Since almost all criminal convictions are considered proof that the applicant lacks "good moral character", it would be a good idea to wait until you have clean 10 years behind you. Second, your conviction will have to be disclosed on the naturalization application. There is a chance that the immigration officer will see "disorderly conduct" and move on. But, if he/she will do his/her job and look at the certificate of disposition, there will be trouble. Our immigration law imposes severe penalties for crimes; the crimes that have anything to do with firearms and explosives are considered "aggravated felonies" and carry brutal immigration consequences. The person does not have to be convicted of such a crime; it is enough that he/she admits committing essential elements of the crime in question. So, if the records of your conviction show that you pleaded guilty to the charges involving an explosive device or material, it does not matter that the conviction was for disorderly conduct: USCIS will consider it an aggravated felony. It also does not matter that your record was expunged: immigration law still holds you responsible. And this conviction not only makes you ineligible for citizenship, it makes you subject to a deportation and a bar to re-entering the U.S. for the rest of your life. If, however, the records show that you never admitted possessing an explosive device or material and only pleaded guilty to disorderly conduct, it should be possible to successfully defend you against deportation for aggravated felony. My advice is to find a good immigration attorney and have him/her request and review your USCIS file and your criminal case records. Obtaining them will take a long time (getting a USCIS record now can take up to 1.5 years), but studying these documents will enable your attorney to give you a definite recommendation.
