Define "inadmissibility" in immigration.

Inadmissibility in immigration refers to the legal grounds that prevent a person from entering or remaining in the United States. This concept is critical in the immigration process, as it outlines specific reasons under U.S. law that may disqualify an individual from being admitted or continuing their stay in the country.

These grounds can include a variety of factors such as health-related issues, criminal convictions, security concerns, and immigration violations, among others. By establishing these criteria, the legal framework helps maintain national security and public safety while regulating who can legally enter or remain in the country. Understanding inadmissibility is crucial for individuals seeking to navigate the immigration system and for legal professionals assisting clients with various immigration matters.
