Let's talk about the immigration status, to begin with.
Do you want to prove your child's U.S. immigration status?
Yes, I have to.
Did you fill out form I-551 Lawful Permanent Resident Card, Machine Readable Immigrant Visa?
Yes, I have that form right here.
What if I'm missing one of the other documents and can't replace them?
That depends. Do you have an employee identification card?
No, unfortunately not.
Do you have a school identification card?
Yes, I have one.
Then you'll only need a U.S. passport in addition to that.
What if my daughter has a social security number already?
