Well, your belief was just wrong. I was speaking out of my first-hand knowledge, in which I KNOW people who got US government funding (by the way, it's more US government funders than Fulbright) and in their waiver process it DIDN'T show "sponsor view".
Two theories:
- That gov funder is no longer operational.
- The DOS reviewer just "forgot" to input that info into the online system.
DOS reviewer division is a very low tech with depleted resource, and made mistakes all the time.
