What is the main purpose of INA 252?

The main purpose of INA 252 is to provide guidelines for detaining illegal aliens. This section of the Immigration and Nationality Act outlines the authority and procedures under which individuals who are found to be unlawfully present or who are encountered at the border may be detained by immigration officials. It establishes the framework for how and when detention can occur, ensuring that there are legal standards in place for enforcing immigration laws.

The other options relate to different aspects of immigration law but do not align with the specific intent and provisions of INA 252. Options concerning regulation of immigration attorneys, issuance of permits for landings, or immigration court procedures fall outside of this particular statute's focus on detention practices for individuals who lack legal immigration status.
