What security-related grounds can lead to deportability under INA 237(a)(4)?

Deportability under INA 237(a)(4) specifically addresses serious security concerns that threaten national security or public safety. Engaging in espionage or sabotage is a direct threat to the integrity and security of the United States. Such actions can have far-reaching implications, potentially harming national interests and safety. The law prioritizes the protection of the country's security, and individuals involved in these types of criminal activities are considered a significant risk. Thus, those found to have engaged in espionage or sabotage can be subjected to deportation as a consequence of their actions.

In contrast, the other options, while they may represent violations of laws or regulations, do not specifically pertain to actions that threaten national security or safety in the same way espionage or sabotage does. Violating employment regulations, public intoxication, and absconding from immigration authorities are handled under different provisions and do not carry the same gravity in terms of security-related deportability.
