Approved F4 Category petition has Scheduled interview at embassy from banned country. Will file be terminated?

[Navid+Tina 3]

My uncle has an interview scheduled in Ankara, Turkey on March 20 for an F4 category visa. He is from Iran and thus barred under the travel ban to enter the US. He may be able to get a visa with a waiver. My question is that if he does not gain a waiver and is denied a visa, what happens to the application? Will it remain on hold until the law changes? Or will it be terminated entirely.

 

Thanks.

I doubt anybody knows, probably put into AP until something happens but that is a guess.

 

Yet to see someone get a waiver, but early days, sounds more remote under F4.
