so U.S. citizens who will give birth in a different country will not be granted jus soli, too?
I have no idea. It varies by country.
This is an interesting discussion on the subject.
https://cis.org/Report/Birthright-Citizenship-Children-Foreign-DiplomatsA lack of direction from Congress has resulted in children born to foreign diplomats on U.S. soil receiving U.S. birth certificates and Social Security numbers (SSNs) — effectively becoming U.S. citizens — despite the limiting language within the Citizenship Clause of the 14th Amendment.That's clearly wrong. A foreign diplomat exempted from US law has a birth here, and the child gets US citizenship?
