If there are no pending updates listed, the section is current as shown. No Pending Updates link is provided for the whistleblower provision of the Sarbanes Oxley Act, 18 U.S.C. § 1514A below.

Each volume of the print unofficial annotated versions of the U.S. Code (U.S.C.A. and U.S.C.S.) is updated annually by either a cumulative pocketpart inserted in the back of that volume or a separate cumulative softbound supplement shelved next to it. These supplements to the hardbound volumes include any amendments or notice of repeal for individual code sections and any new research resources or case notes that have been added to a code section's annotations since the hardbound volume was last published.
The most up-to-date annotated codes are available on Westlaw (U.S.C.A.) and Lexis (U.S.C.S.). Additionally, when using Westlaw or Lexis, you can use their citators to check for pending or very recent changes to a federal statute (See Updating Federal Statutes & Finding Other Resources Using Citators (KeyCite & Shepard's)).
