Any citizen of the world is entitled to residency in the United States?
Are we entitled to stop them at the border and at least ask a few questions?
Do we have to provide transportation to the nearest hospital for free treatment of any condition that they brought with them?
Do we have to provide ballots in their native language?
If they are above 65 years of age, will they qualify for Social Security and Medicare?
Aren't we marvelous.
