I suspect that there is an issue with his birth certificate or verification of his birthdate at some level. Revealing that may undermine his elegibility during his HS years, Oregon years, and ultimately his sponsorship potential as a pro. It's lso not likely his fault as determining your birthdate in Kenya has been a challenge; birth certificates are not always issued in Kenya, especially in rural areas like where he's from.
