I would guess that it depends on how his foster parents view their relationship with him: do they consider themselves to be his family? They may be worried about your influence in his life, not knowing who you are or your circumstances (I'm not sure if they do). Why was he adopted initially? The social worker probably has the clearest view of what she feels would be best for him given that she can see all sides of the situation. However, if he is 18, he is legally free to look for you. If he hasn't inquired as to your whereabouts then that is a decision that has to be respected. I would suggest leaving a letter with his social worker so that if he approaches her, she will have something immediately at hand. There is no reason a letter from you and his brother cannot be included in his case file. Good luck.
