“I would allow *elderly* parents, minor children, and spouses, ...”
None of this is in the US Constitution.
THERE IS NO HUMAN RIGHT TO COME TO/LIVE IN THE UNITED STATES !
It is true that no one has a right to go off and live in a particular place; however, this ought to be at a minimum a family-oriented society, and for this reason, I think spouses and minor children ought to be able to enter with someone who comes here legally. And as a Christian, I believe we have certain obligations to our parents, so if they are elderly, we ought to care for them.
I do not think that every niece, nephew and 14th cousin three times removed ought to be able to come in under family reunification: that is just silly.
If we allow someone to come here, I think this small number of relatives should be able to join them. Now the situation is that a huge number of relatives can come in; I am suggesting a reduction.
