Citizenship Through Grandmother/Mother

[Matt70]

Sorry if this is the wrong section but this is a tricky situation and I am confused. Hopefully you guys will be able to help me. The grandmother is a US citizen who moved to Mexico and got married. She had a daughter but never did anything to get dual citizenship. The daughter grew up not knowing that her mother was a US citizen and later on had 3 kids in Mexico. We can get citzenship for the mother but we facing a problem with granting it to the son of the mother. Now we trying to see what options we have because the mother did not live in the United States prior to giving birth. Is there a way around it because she didn't know that could've been a US citizen.

Just to clarify: Generation 1 is the Grandmother who was born in the United States. Generation 2 is the Mother born in Mexico. Generation 3 is the son born in Mexico that we are trying to get Citizenship for.

Thank you guys for any help you guys offer. I know immigration is a very difficult situation. I tried looking online but I can't find much information on it.

The mother (Generation 2) is almost certainly a U.S. citizen from birth, because the grandmother probably met the residency requirements to pass on citizenship. Generation 3 probably do not have U.S. citizenship from birth, because the mother did not live in the U.S. for the necessary period before she gave birth to Generation 3. There are two paths to U.S. citizenship for Generation 3:

1) Through N-600K. It's a process where a non-citizen child of a U.S. citizen can use the time spent in the U.S. by a grandparent to qualify. After it's approved they will have to travel to the U.S. to take the oath to become U.S. citizens. The child (generation 3) must be under 18 to do this.

2) Normal green card route. The mother (U.S. citizen) applies for a green card for her children (Adjustment of Status if they're in the U.S.; Consular processing if they're not). That would require the mother to live in (or plan to return to live in) the U.S. If they are under 18, once they become permanent residents (either AOS gets approved or they enter the U.S. on an immigrant visa), and are living with their citizen mother in the U.S., they immediately become U.S. citizens through the Child Citizenship Act of 2000.
