If by INS you mean Immigration and Naturalization services then no. The INS does not exist. Immigration is now handled by the Department of Homeland Security which heads USCIS (they process affirmative immigration applications) and ICE (which enforces immigration laws) and the Department of Justice which heads EOIR (who adjudicates immigration cases).

USCIS stands for United States Citizenship and Immigration Services. This is the governing body which regulates the immigration issues and takes care of the naturalization process.
