So if YOU have a relative or friend over seas who wants to come here and immigrate to the USA we can tell them to stay home ? We don’t need them ? don’t come here ? your not welcomed ?
Yes, Americans have no obligation to allow any foreigner into the country.
This is an important question in the Western world: will we allow mass immigration to swamp the electorate and change our country’s identity.
A pathway to legalization and citizenship is a pathway to exercise political power. This country more and more resembles a third world country. I’m old enough to see this happening.
In the "old" days of Ellis Island you had to have a sponsor to live with in the USA. If we go back to that system then your hypothetical relative is welcome. But since we ditched that system they can sty where they are.
