I got a dui 15 years ago. I then got a deferred prosecution agreement where I plead guilty to the charge and then the case was dismissed after I met the terms and conditions of the agreement. 7 years ago I got a green card with no issue. My attorney then stated that I was arrested and the case was dismissed. He went on to say that there was no conviction for immigration purposes. I am planning to apply for citizenship and reading through the USCIS manual, I don't know whether to say that I was convicted because of pleading guilty in the deferred prosecution. I have the court and police records to attach with my application. Any help?
