The U.S. Immigration System: Agencies, Terms, and Decision Points

This lesson gives students the operating map for the U.S. immigration system before they study individual visa categories. It explains which agencies make which decisions, how a visa differs from immigration status, and why the same person may face separate decisions at petition filing, visa application, admission, extension, change of status, adjustment of status, and removal-risk points.

Students learn practical vocabulary used throughout the course: immigrant and nonimmigrant intent, sponsor and beneficiary, petition and application, priority date, status, authorized stay, unlawful presence, consular processing, adjustment of status, and admissibility. The goal is not to choose a visa yet, but to understand the decision architecture that makes visa planning possible.
