This is a strange situation. Child became an LPR as a Special Immigrant Juvenile. He was REMOVED from an incapable or unfit parent. That parent later naturalized and an N-600 was filed based on the unfit parent's naturalization. She did not have legal or physical custody as required. This raises more questions: Did she disclose this situation about her child during the N-400 process and should it have been an issue as to GMC? Was the SIJ route taken fraudulently? Something is not right here.
