How CitizenApproved decides what is authoritative
Citizenship information becomes dangerous when a proposal is labeled law, an old form instruction is treated as current, or an agency webpage is presented as if it outranks a court holding. This page shows the source discipline behind the site.
Binding interpretation depends on the court
Court decisions
Courts interpret the Constitution, statutes and regulations. Supreme Court holdings bind nationwide on federal questions. Courts of appeals create binding precedent within their circuits; district-court rulings have a different reach. A judicial holding is not “below” an agency policy manual.
Legally binding agency rules when valid
Federal regulations
Title 8 of the Code of Federal Regulations contains rules implementing the Immigration and Nationality Act. Regulations must be read consistently with controlling statutes and judicial decisions.
Operational authority and agency interpretation
USCIS policy, forms and instructions
The USCIS Policy Manual, form instructions, fee schedule and official alerts explain how USCIS currently administers the law. They matter enormously in practice, but they are not interchangeable with statutes or regulations.
Not current law merely because published
Proposed rules and announcements
A notice of proposed rulemaking explains what an agency may change. It does not become an operative rule unless the agency completes the rulemaking process and a final rule takes effect.
CitizenApproved research rules
- 01State the rule that governs today before describing proposals, political arguments or historical alternatives.
- 02Prefer the primary text: Constitution, statute, regulation, opinion, form instruction, fee schedule or official policy alert.
- 03Record a verification date for facts that can change, including fees, tests, processing practices and current officials.
- 04Separate legal eligibility rules from evidence requirements, filing mechanics and agency processing guidance.
- 05For historical citizenship claims, identify the law in effect when the relevant birth, naturalization, custody or age event occurred.
- 06When authorities disagree, describe the conflict and the jurisdictional posture instead of manufacturing “balance” between unequal authorities.

A note on secondary sources
Congressional Research Service, GAO, CBO, academic scholarship, legal treatises, nonprofit organizations, advocacy groups and news reporting can add valuable history, empirical context and competing interpretations. CitizenApproved may use them for context, but a secondary source does not replace the primary authority when the primary text is available.
For practical legal help, USCIS also maintains information about finding authorized legal services. Only attorneys and DOJ-accredited representatives may provide immigration legal advice in the roles permitted by law.
