My son who is 14 and a “III” was held up briefly by US immigration when coming in with his father - the “Jr” because he looked nothing like his 10-year old self in the photo. He was asked for a second ID like a school card and was then advised to get a new passport. It was all fairly light hearted but odd. Not going to happen until next year, as I’m pretty sure when he was 4 he looked a lot different than the photo of him at 5 months on his original passport. I understand 5 years for kids since they change so much, but five years is five years.
