I do also think it’s not as simple as “they should follow the process”. A lot of those people are refugees _directly because of the US_. We backed their governments military dictatorship in the Face of a democratic coup, resulting in years of brutal reprisals by security forces, eventually leading to El Salvador being the absolute clusterfuck it currently is.
The same vague story applies to several South and Central American countries.
We owe those people. It was a terrible thing to do, and has caused decades of suffering. I’m not sure if the solution is citizenship, but I don’t think we can just tell them to go fix it themselves.
