I work for a local county government. I have never heard this new constitution.
Currently, the 14th Amendment of the U.S. Constitution guarantees citizenship at birth to almost all individuals born in the United States or in U.S. jurisdictions, according to the principle of jus soli. Certain individuals born in the United States, such as children of foreign heads of state or children of foreign diplomats, do not obtain U.S. citizenship under jus soli.
In other words, except for the cases of foreign diplomats, as long as a child is born in the US or in other US territory, the child is US citizen at birth. But foreign parents of a US born child are not eligible for citizenship until the child is 18 years old to be qualified to sponsor his/her parents naturalization applicantions.
