Can too many parking tickets affect Green Card or Citizenship process?

I think it has no effect. Parking tickets are simply non-moving violations.Either you parked in the wrong place or the meter ran out after you parked.However, there are two components to moving violations. There is recklessness which can become criminal and that could become a major issue by itself or many speeding tickets that are not criminal could lead to a conclusion that you are not a person of good moral character.
