Immigration into California, and resulting overrun of that state, does not imply that other states must take and allow California's own overflow into their states. States were more than able to exclude persons from their own territory, and did, as they had original sovereign authority over that specific territory, and still do.
The result would be California would be forced choke to death on its own immigration, and those government officials allowing it wold be ousted, This is far preferable to the federally imposed suicide pact we have now, where the federal government is allowing the states to literally be invaded deliberately unchecked immigration, and without legitimate authority prohibiting states from preventing immigration into their own borders, meanwhile states like California are drawing in persons with sanctuary from what little law exists, and then providing licenses and identification, and overflowing those persons into other states.
Yes, it is the duty of the federal government, along with upholding all laws, and the Constitution itself. However unchecked entry into the country is not "immigration" at all, nor is it naturalization. Yet the federal government has corrupted and usurped both of these authorities and is using them to not only subvert the country, and state powers, but also openly to subvert the elector process itself, with the long-term goal being the entire subversion of the Constitution and institution of a populist democracy where no real individual rights exist.
This is the "slippery slope" that has now become nothing but a mud slide as a result of allowing the federal government authority that it nowhere has. Nowhere in legitimate federal authority is the ability to "immigrate" people into states, when the territory of those states is the sovereign domain of each state, and not the federal government itself.
Because we all know that Madison's view of federal authority, (or any one person's for that matter) is synonymous with the Constitution <ref: Virginia Plan>?
Beyond that, the 1790 Act was
not at all an immigration law, but was nominally, and in application,
a naturalization law, the 1790 Naturalization Act, and specifically dealt with the process of becoming a citizen, not immigration itself.
Furthermore, that 1790 Naturalization act was so poorly phrased, that it had to be rewritten nearly verbatim only 5 years later, with the 1795 Naturalization Act specifically repealing the previous act. The reason for the entire repeal of the 1790 Act, and its rewrite, even poorly understood by some "scholars" today, is the fact that the
1790 Naturalization Act indicated the following:
And the children of citizens of the United States, that may be born beyond sea,Also, children of citizens born beyond sea, &c. or out of the limits of the United States, shall be considered as natural born citizens: Provided, That ...
Many so-called 'scholars' even now believe that reference to "natural born citizen" in this naturalization act was actually defining, or changing, the terms of natural born citizen, to actually confer that status on those born overseas, which is unreasonable given the fact that natural born citizen, is a term of art existing in natural law, and
by definition entirely outside of, and beyond the reach of, man-made Positive Law. The 1790 Naturalization Act did no such thing.
In point of fact, and congruent with the language of the times, the legislators were not extending natural born status to those born overseas, were not conferring natural born on those who had never even seen this country, even before the ink was dried on the Constitution, but were using the more common practice of using SIMILE, comparing two fundamentally unlike things, to argue the right of
only citizenship for those born overseas, and not awarding them actual natural born status. The phrase "considered as" is employing that simile to argue for mere citizen status, and not indicating those persons equate to natural born citizens; "considered as" does not equate to "now become".
As a result, all reference to "natural born" was removed in the 1795 Naturalization Act, and deliberately, at its onset, repealed the entirety of the 1790 Act, with very little else changed, being otherwise a verbatim repeat of the 1790 Act.
Naturalization is a power. Immigration is not a power, and does not relate to naturalization. People can, do, and have entered a country without the intention of being made citizens thereof, and are referred to as denizens. In fact the only power under "naturalization" is only to create a "uniform rule" of naturalization, i.e. minimal standards for citizenship, and not to dictate all terms of naturalization, nor to take over naturalization itself.
Citizenship was originally exclusive recognized by the states, and then all citizenship and other documents, were recognized across each and every state, and citizenship not being the exclusive domain of the federal government. Persons were first citizens of a state, and then by virtue of that citizenship, only then citizens of the United States <plural>.
