But over the years things have changed. For example, when I lived in Germany as a military dependent (1960), we were told that if our mothers gave birth, their children would not be eligible to be POTUS. They would be considered citizens of Germany and the US. The US, at the time, didn’t consider dual citizenship … many pregnant wives went back to the US to give birth.
“Natural Born Citizenship” means that YOU HAD TO BE A CITIZEN AT THE MOMENT OF BIRTH -—
In other words, citizenship can not be granted by naturalization or legislative act, at any time AFTER birth!
