America's Immigration Policy reflects International Policy on Immigration. There are two classes of Immigrants, Documented and Undocumented, neither are illegal. Unfortunately the system is under constant abuse by the later group and Biden is finally taking action to correct that once and for all. Trump bad mouthed them but actually sabotaged the Immigration apparatus to deal with them making things worse. Given the plight of the planet with global warming I believe we are just starting to see the tip of the iceberg here and things will become far worse before they get better. Hopefully there is light at the end of the tunnel.
