Trump's Executive Order excludes children born to visa holding parents from being US citizens, unless one of them is a citizen
Among the categories of individuals born in the United States and not subject to the jurisdiction thereof, the privilege of United States citizenship does not automatically extend to persons born in the United States: (1) when that person’s mother was unlawfully present in the United States and the father was not a United States citizen or lawful permanent resident at the time of said person’s birth,
or (2) when that person’s mother’s presence in the United States at the time of said person’s birth was lawful but temporary (such as, but not limited to, visiting the United States under the auspices of the Visa Waiver Program or visiting on a student, work, or tourist visa) and the father was not a United States citizen or lawful permanent resident at the time of said person’s birth.
Unless one parent is citizen, the child born will not be a US citizen.
Interesting to note this is same process India uses to determine citizenship of a child born in India (Jus sanguinis)
