What does the acronym NS refer to in the context of U.S. immigration?

In the context of U.S. immigration, the acronym NS stands for National Security. This term is crucial because it encompasses the measures and considerations that the U.S. government takes to protect the nation against threats, including those related to immigration. National security influences various immigration policies and processes, as the government must ensure that individuals entering the country do not pose a risk to public safety or national sovereignty.

Understanding national security is essential for asylum officers and other immigration personnel because it helps guide their decisions when assessing cases, particularly in situations where an applicant's background or country of origin might raise concerns regarding security threats or potential harm to the U.S. and its citizens.
