There are things that are illegal that lack an enforcement mechanism - that doesn't make them not illegal, it just means that there's not a legally enforceable consequence for doing the illegal thing. International law is a really, really complex subject for exactly that reason - nearly every obligation or commitment in international law lacks an enforcement mechanism that parallels what you would find within a national legal system.
International law is many things. It's also NOT many things.
It doesn't trump the US Constitution, which makes the Chief Executive responsible for the defense and protection of the United States.
It's also not a suicide pact, whereby a nation has no say over how it oversees its borders or residency parameters.
