Which the US adopted - by treaty, along with the UN Charter, and various other conventions.
But the US also accepts Asylum seekers and Refugees, and allows their claims to be made, wherever they make them, without regard to how they entered, under US Law.
And when Trump refused to allow the migrants (fleeing US Drug Cartels and Gangs and the NarcoDictatorship installed in Honduras, by Obama and Killary) to enter and make asylum claims - it was he who was breaking the law.
And all of the mania over the policing of the undocumented, led to a whole lot of Georgia Peaches, rotting in their orchards. And it's that kind of Big Government that will eventually be creating the cage that YOU are trapped-in. Peter Thiel wants an electronic Technocratic slave society. And Trump's wall, will prevent YOU from escaping it.
Where was all of this concern on the right, for illegal border crossers, when Luis Posada Carriles openly admitted to illegal entry - after being broken out of a Jail Cell, and fleeing Justice systems of multiple Countries in Latin America and the Caribbean.
Well... For one thing - I live in the greater LA area - so I've seen the completely delusional, Branch Covidian headlines and Op-eds, all along.
In fact, my father even wrote one of them, it was objectively advocating for MALPRACTICE, both in terms of Medicine, Public Health Policy, and Public Policy, more broadly.

There was a State Department Memo, written by NeoCon Chicken Hawk Brian Hook, to explain "Human Rights" to Rex Tillerson. It stated in plain language, the official-unofficial policy of the US Government. We ONLY talk about the (alleged - often bullshit) Human Rights abuses of our enemies. We never mention, even the proven Human Rights abuses of our allies (unless we want to pressure them, into following our orders, better).
"The International Community" is constantly shrinking... And the bodies are ALL-rigged by the Empire.
