Nice idea but would never work and probably illegal.
Just like now, you can lie.
ie the “Seeking Asylum” group.
I’m pretty sure such individuals do not have the Constitutional protections of speech.
BTW, this would be the one pro-speech cause the loathsome Woke Rats would fight for.
If you’re from El Salvador and you’re at the Mexican / US border it does not matter if you lie because you cannot seek asylum to the US (and most other nations) if you’re already outside the country you’re trying to escape.
Unfortunately, Biden ignores this.
