Hello. I am currently stuck in the same situation as you were in. I am an American citizen by birth and I have given birth to my child out of country with my spouse who is a non citizen. I tried to do the CRBA procedure for my child but I moved abroad when I was 15. Therefore I do not meet the requirements of physical presence of the CRBA. I recently found out that the option of my father applying through N-600K is also available. As my father is also a citizen. Neutralised however. I just wanted to ask that it doesn’t make a difference if my father is a neutralised citizen and if all of the 5 years of physical presence are after the age of 14. He is an American citizen and he has been living in the USA for decades now. Please let me know. Thankyou.
