NSF Issues Grace Period for Important Notice No. 149

On December 5, 2025, NSF notified the research community that it is offering a grace period for enforcement of Important Notice No. 149 for proposals submitted between December 2 and December 31, 2025, to accommodate programs with deadlines near the December 2, 2025 effective date. NSF will continue to accept proposals using the previous Biographical Sketch and Current and Pending (Other) Support forms until December 31, 2025; after that date, all proposals must incorporate the new senior/key personnel certifications (research security training within the past 12 months and not being a party to a malign foreign talent recruitment program) required under Important Notice No. 149.
