Which category does the INA define as ineligible for certain immigration benefits?

The Immigration and Nationality Act (INA) specifies that individuals who have committed certain crimes involving moral turpitude can be ineligible for various immigration benefits. Moral turpitude generally refers to conduct that is considered contrary to community standards of justice, honesty, or good morals. Certain offenses classified under this category can impact a person's immigration status, including their ability to obtain visas, adjust their status, or achieve lawful permanent residency.

Those who fall under this definition may be denied certain immigration benefits because the U.S. government has a vested interest in ensuring that individuals with such behaviors do not gain legal status or protection in the country. This is rooted in the principle of maintaining the moral fabric of society and protecting public safety.

In contrast, lawful permanent residents, non-immigrants, and refugees are not automatically categorized as ineligible for immigration benefits based on the same standards. While they also have specific rules governing their immigration status, it is the actions related to crimes involving moral turpitude that distinctly highlight a reason for ineligibility.
