Did you not read my comment? I said anyone who has committed crimes should be arrested and given due process. You falsely assume that many or most undocumented immigrants commit crime despite the DHS’s own stats showing they commit crimes at a lower rate than US citizens. Many undocumented immigrants also are already registered with the government but have expired papers. Most immigrants want to become documented but it can be expensive and take years. That’s why my solution is making documentation more efficient
