“George Romney, Mitts father - was a U.S. citizen at birth.”
Wrong.
According to Mexican law, having been born in Mexico, George was a Mexican citizen.
If what I read was correct, the first Romney to hit Mexico relinquished his U.S. citizenship when he moved there with his 7 crazy wives.
Do your homework on Mexican law. Quit repeating garbage of which you have only heard.
Georgie’s father was a Mexican citizen. This cancelled out Georgie being a U.S. citizen.
Also do a little reading on American law.
By the way, there are over 90 families with the surname Romney in Mexico. According to you, they also must be American citizens.
Do some reading.
U.S. law prevails - despite any foreign law.
Those born of two U.S. citizens, provided that the parents have ever legally resided in the USA, are citizens at birth no matter WHERE they are born according to U.S. law.
I recommend you do a little reading on U.S. law and recognize that it is not subservient to foreign law.
