I see. Let me ask another question. for the passport. I see, thank you. And since you are not a citizen, what documents would you have to apply, please?
Well, you'll need to show you current inmigration document, as specific as it get, you need Form I-551, Immigrant Visa and I-766, EAD or work permit.
You said before, a federal law could require me to provide a SSN in order to get some benefit, right?
That's correct. Some government benefits or services, requires from you to provide a SSN. That's regulated by federal or local law.
