I am an natural born american citizen, my mother and father are both natural born american citizens. I had a daughter and son, one american and one canadian both with same mother. My son now 27 and unmarried would like to file a citizenship claim if possible. He was born in Canada, although he lived in United States for about a year at age 1-2. I had him when I was 22 yrs old in wedlock and stayed married to his mother for 4-5 years. Does he have a claim and what is best route to get process started.
Thanks in advance for any help with this.
