On November 25, 2025, the National Science Foundation (NSF) released an update to the agency's Important Notice No. 149. The update states that the requirements originally slated to take effect in October 2025 instead take effect on December 2, 2025 as a result of the recent government shutdown. The impacted requirements include: certifications of research security training for senior/key personnel; institutional certifications regarding contracts or agreements with Confucius Institutes; and recipient institutions providing supporting documentation for senior/key personnel activities reported as current and pending (other) support (e.g., contracts, grants, appointment letters) to NSF, upon request.
