Do you want Congress and the President to restrict immigration?
If so, under what provision of the Constitution do they have the authority to do so?
The Constitution gives control over immigration and naturalization to Congress.
Which is why Cruz was made a citizen, by virtue of the immigration and naturalization laws duly passed by Congress.
If the statute had read differently, as it did at other times in U.S. history, Cruz would not have even been granted citizenship, much less have been considered “natural born.”
