Denial due to visa overstay as a child
A colleague / friend applied for Global Entry and did the interview but was denied. At the interview, the first line of questioning led to him disclosing that he'd been brought to the US as a child (4 or 5 years old) on a tourist visa, and that he had remained in the US until marrying a citizen several years ago, becoming a permanent resident and ultimately naturalizing. My understanding is that the rest of the interview went smoothly.
The denial letter listed 'Visa Overstay' as the reason, but given that it happened as a child, it seems like an ungenerous interpretation. Does he have any hope of success in appealing to the ombudsman, emphasizing that he was a young child when brought, and that he did not knowingly overstay?
