Usually, an overstay raises red flags if another request is made to visit. In addition, overstaying and then leaving could carry with it a bar to reentry. However, a minor does not accrue unlawful presence so under your facts, the person you are referring to would not have the bar. Decisions on these are made on a case-by-case basis -- does he have ties back in his home country strong enough to ensure his return, etc. If he is friends with the interviewing officer -- perhaps but the officer could get in trouble if he used favoritism to make a decision and this is discovered. Please consult a good immigration attorney if in doubt.
