What affect does a misdemeanor charge have my US citizenship application

If you disclosed the incident when you applied for your permanent residence, it should not have much effect upon your citizenship application. The period of time required for an applicant to demonstrate good moral character is usually 5 years, and if you have already met that and have had no other incidents with the law, you would generally be found to have good moral character.
