IDK
Chapter 3 - United States Citizens at Birth (INA 301 and 309)
No mention of a child born in the USA to citizens of other nations.
MT's father was completing a medical residency, a defined
short-term stay in the US.
The parents may have had the option to decline US citizenship for the child.
Apparently MT lived in Argentina. IDK much about this, but possibly to have dual citizenship of Venezuela & Argentina, any citizenship of the USA was ended?
The linked policy also suggests that a child born to citizens of another country with a
diplomatic passport are citizens of their parents' nation. Again, IDK much about the government of Venezuala in 1974, but was Dr.T sent for this residency on a diplomatic passport? Was the parents' promise that there would be no "anchor baby" a condition of Dr.T & Mrs.T leaving Venezuela for the USA?
(My family has some experience with refugees from Chile in the early '70's....)
Articles state that MT
is a citizen of Venezuela. There seem to be several possible reasons for this.
Apart from FD's suggested citizenship in Greece, Turkey, and the USA!
