The main purpose of this legislative text is to amend current immigration laws in the United States by eliminating immigration detainers. Immigration detainers are requests from federal immigration authorities to local law enforcement to hold individuals suspected of being in the country illegally, often leading to their detention and potential deportation. The key provisions of this legislation include the removal of specific paragraphs and subsections from the Immigration and Nationality Act that currently allow for the issuance and enforcement of immigration detainers.
