What organization verifies the documents for lawful entrance into the U.S.?

The correct choice is Systematic Alien Verification for Entitlements (SAVE), as this program is specifically designed to verify the immigration status of individuals applying for certain public benefits in the United States. SAVE operates under the U.S. Department of Homeland Security and provides a mechanism for government agencies to confirm whether an individual is legally present in the U.S. and eligible for entitlements.

The other organizations mentioned, while related to immigration and entry into the U.S., serve different purposes. The Department of Homeland Security oversees various aspects of immigration and border security but does not specifically focus on the verification process for entitlement programs. Immigration and Customs Enforcement (ICE) is primarily responsible for enforcing immigration laws inside the U.S. and handling removal proceedings rather than verifying documents for entitlement purposes. U.S. Citizenship and Immigration Services (USCIS) manages the application processes for immigration and citizenship but does not directly verify documents for the purpose of entitlements like the SAVE program does.
