Advanced Interested Government Agency Waivers
How Does NSF Review an Interested Government Agency Waiver Request?
NSF currently uses a two-part IGA review process: an initial eligibility screening followed, if invited, by a full package review. A favorable NSF review results in an IGA letter to DOS.

Phase one is eligibility screening
Current NSF guidance requests an inquiry form, the J-1 holder's current curriculum vitae, and a sponsor letter describing the person's research and relationship to NSF.
NSF evaluates the federal and scientific interest
The sponsor should explain how the research serves NSF and national interests and why the applicant's absence for the residence requirement would be detrimental.
Phase two follows only if NSF invites a full application
If NSF determines the case passes initial screening, the sponsor receives instructions for the complete package and additional supporting documentation.
A favorable NSF review produces the agency letter
NSF states that if its full review is favorable, it will issue an IGA letter to DOS recommending that the waiver be granted.
