Hi everyone, I received an NSF fellowship for 2012-2015, which started in the fall of 2012. I recently received an offer for an industry internship for the summer of 2013. I understand that I will need to forfeit my NSF fellowship stipend for the months that I am working. I was wondering if anyone here has had experience filing for forfeit status, and what that entails in terms of full-time enrollment status, etc? Any insight would be much appreciated. Thank you very much!
