This question arises from the current regime's efforts to reverse naturalization.
For anyone who has one US citizen parent and one non-citizen parent, where the citizen parent has passed before the child applicant for naturalization reaches 18 years of age, resulting in the applicant applying for and receiving naturalization as an adult, can that same currently naturalized citizen also obtain natural born citizenship status through the deceased citizen parent and would it be advisable?
If I understand you correctly, you are asking whether the naturalized citizen was a citizen at birth based on his or her father's citizenship. To answer that question, we would need to know when the naturalized citizen was born and the countries where the naturalized citizen's U.S. citizen parent lived from birth until the birth of the naturalized citizen.
Thanks, you got it right. 1970 is the birth year and father lived in the United States for decades prior but had a child while out of the country, the naturalized citizen. The question is really about whether natural born citizenship is available to children of an American citizen when the child is born abroad, but the parent was deceased before majority age. Naturalization would probably be sufficient, but given that even naturalization is theoretically at risk, maybe obtaining outright natural born status is better insurance. There is an N-form for this sort of thing.
