It is “an act to establish an uniform rule of naturalization”, which is the sub heading of the act referred to as “The Naturalization Act of 1790”.
The persons described therein are naturalized. Congress conferred the status “citizen” on some and “natural born citizen” on others.
This Act was repealed in 1795 and there has never been any other Act conferring the status “natural born citizen” on any persons. If fact the same set of persons upon which the 1790 Act conferred the status “natural born citizen”, had the status “citizen” conferred upon them by the 1795 Act. The 1952 Act also confers the status “citizen” on this set of persons.
Why do YOU think that there is a discussion of who shall be natural born citizens in the Naturalization Act of 1790?
