Thats essentially how Russia treats all their citizens especially male, although for different reasons but that’s why I haven’t been back.
If you’re born there you are essentially theirs whether you denounce the citizenship or not and they would try to keep you there, especially if you’re still in the mandatory draft age.
At least US is being nice about it and giving him a heads up.
What I don’t agree is in making a case out of him specifically and not a general rule, unless I misread something.
Edit: you mean Rocket instead of Gundam, their sigs got you confused :lol
Well they intend on making it a new law now because of how much publicity he’s getting from denouncing citizenship. Note the bold in OP how they’re calling it the “Ex-Patriot Act”.
