6 U.S.C. § 291 — Abolishment of INS

(a) In general: Once every function has been transferred out of the Immigration and Naturalization Service, as this chapter requires, the Immigration and Naturalization Service inside the Department^* of Justice is abolished — it no longer exists.

(b) Prohibition: The general reorganization power in section 542 of this title can be used to reorganize functions^* or offices within the Bureau of Border Security or within the Bureau of Citizenship and Immigration Services. But that power cannot be used to merge the two bureaus back into one agency^*, and it cannot be used to combine, join, or consolidate functions or offices from one bureau with functions or offices from the other.
