America welcomes immigrants that can become regular productive US citizens. What crosses our borders illegally now can't even read or write a word in their own native languages. That is the big problem. Who wants to come here and excel just to pay high taxes to support the needs of essentially street bums? I believe you are wrong. Your view?
"Your view?"
The main problems that mass immigration brings are not those of terrorism, but rather, crime, job loss, educational chaos, language barriers and cultural erosion.
Third World illegal immigration also brings a massive subculture of unassimilable people inside the country.
American don't like their nation being colonized by an alien, 3rd world mass that speaks a different language, imports different values and often is loyal to a different country.
High time we plugged the floodgates before the torrent becomes a tsunami.
Current legal immigration policies and laws it's what will eventually, though, change us into another Third World country.
