One question, one specialist guide.
Each site goes deep on one part of U.S. citizenship law, with the statutes, forms and court decisions that apply to it.

Form N-600
Certificate of Citizenship
For people who may already be U.S. citizens through a parent, by birth abroad or through a parent's naturalization. Form N-600 doesn't make you a citizen. It proves you already are.
