Barron isn't eligible. The only one of President Trumps children who is would be Tiffany when she's old enough in ten years.

Barron isn't eligible.

I checked, some months ago. Melania received her citizenship before Barron was born. By a few years, IIRC. He and Tiffany are both eligible. Or will be, eventually.
