When is the deadline to submit the NSF fellowship annual activities report and declare fellowship status(for previous fellows)? I am a fellow who just completed the first year of the fellowship. I received two emails saying the deadline is May 15th, but the most recent program solicitation here https://www.nsf.gov/pubs/2018/nsf18573/nsf18573.htm says the deadline is May 1. Which one is it? Is there a distinction between when the annual activities report is due, when it has to be approved by, and when the completed report and the declaration of fellowship status have to be completed by?
