He was adopted by his grandparents (grandfather us citizen by birth, grandmother by marriage) in 1997. Brought here in 2003 and went into foster care in 2005. He is unable to locate them now. I would like to support him getting citizenship but we are unsure if he, due to being adopted before age 16, is entitled to it through them. I will be adopting him as an adult anyway, but would like to make sure if anything happens to me he is taken care of.
