There should be a country quota AND a very strict set of border and domestic regulations for illegal trespassers.Illegal immigration is a problem on its own and is dealt with separately. Country quota may act to increase the risks of illegal immigration and corresponding govt bodies and offices should act accordingly. I know you don't mean to say "country quota increases illegal immigration and that's why there should be no country quota". There should be a country quota AND a very strict set of border and domestic regulations for illegal trespassers.
history and current situation proves they both never work good together
