It was the law before, America has to allow people to seek asylum, all countries do and you can't lock up toddlers in cages alone FFS.
As I said, put your focus on those who employ undocumented workers, no jobs, no problem and do what Biden is doing, promote better living conditions in these countries and stop them in Mexico instead of on the border. As the drought out west worsens, the farmers will be cut off from irrigation water first and they are just about out of water now. However there is a big demand for employees, unemployment is at historic lows of around 3% and wages are increasing. So these people will be working fast food, construction and a host of other jobs, because there is no one to fill them. The undocumented tend to be brown and the legal ones are brown too, but much better educated, they are the ones you will be working for. Anyway you look at it, they are taking over and you will be replaced, add to that the liberal white youth that media and the internet has been creating for decades and things are looking bleak for the bad guys.
