What are grounds for deportation under U.S. immigration law?

The grounds for deportation under U.S. immigration law primarily involve violations of immigration laws, criminal activity, or security concerns. This encompasses a range of actions that can lead to the removal of an individual from the United States. For instance, if a non-citizen is found to be in the country unlawfully, whether through overstaying a visa or entering without inspection, that would constitute a violation of immigration laws.

Criminal activity is another significant factor; if an individual has been convicted of certain crimes, particularly those that are classified as aggravated felonies or crimes involving moral turpitude, this can trigger deportation proceedings. Furthermore, security concerns, such as involvement in terrorist activities or threats to national security, are also grounds for deportation.

The other options presented do not align with the established grounds for deportation. For example, while violations of international treaties could have implications for foreign relations, they do not generally serve as grounds for deportation under immigration law. Additionally, commercial partnerships and employment status, unless connected to illegal work or fraud, do not directly lead to deportation. Thus, the complexities of immigration law underline why violations of law or security concerns are pivotal in determining deportability.
