The courts will have the final say regardless. Any law or executive order will be challenged in the courts. We literally have tens of millions of US citizens who have received citizenship this way, jus solis, vice jus sanguinis.
We grant US citizenship to anyone born on our soil except for the children born to diplomats and other foreign government personnel assigned to the US.
“The courts will have the final say regardless”
Only if the executive and legislative branches let them. See how that works? No, you probably don’t.
“We grant US citizenship to anyone born on our soil”
Without any statutory authority. Isn’t lawlessness grand? /s
