Which federal court's precedent decisions are binding on all USCIS field and service center offices?

The U.S. Supreme Court is the highest court in the federal judiciary of the United States, and its decisions set binding precedents that must be followed by all lower federal courts, including those serving USCIS field and service center offices. When the Supreme Court issues a ruling, it establishes legal principles that are applicable nationwide, ensuring consistency and uniformity in the interpretation of federal law across all jurisdictions.

In contrast, decisions from lower courts, such as the 7th Circuit Court of Appeals, only bind the federal courts within that specific circuit and may not be applicable in other parts of the country. Similarly, a federal district court's decisions, including those from Wyoming or any state supreme court, do not hold the same authority on a national level and can only influence the interpretation of the law within their specific jurisdictions. Thus, while those courts' rulings may be significant, they do not possess the binding power over all USCIS offices that decisions from the U.S. Supreme Court do.
