What is the process whereby USCIS can have unusually complex or novel issues of law or fact addressed by the appropriate appellate authority?

The process whereby USCIS can have unusually complex or novel issues of law or fact addressed by the appropriate appellate authority is known as certification. Certification allows USCIS to elevate certain cases to a higher authority within the agency, typically when the cases present significant legal questions or implications that go beyond the standard decision-making processes. This mechanism ensures that complex issues are handled with the necessary authority and expertise, promoting consistency and clarity in the application of immigration law.

In contrast, adjudication refers to the general process by which applications and petitions are reviewed and decided. While appeal is also related to contesting decisions made by USCIS, it typically involves cases where an applicant disputes a decision rather than cases initiated by USCIS seeking authoritative guidance. Resolution, while related to finding solutions, does not specifically refer to the formalized means of seeking appellate review for complex cases as certification does.
