Green card interview following 5 year ban?

Hello

I will try to be to the point. This past July, my friend overstayed by two weeks on his I-94. He was going to school in the US. When he tried to re-enter, he was given expedited removal and banned for 5 years. However, he is coming due for his green card interview and they are beginning to process his paperwork. How does the ban affect what will happen with the green card interview? Has anyone had any experience with this sort of situation? Any feeback would be very much appreciated.

Thank you

On what basis is his GC interview? marriage to a US citizen? I am assuming he is doing CP, if it is a marriage based GC

His mother is a us citizen. Sorry I did not clarify.

Its interesting he was banned for 5 years with just 2 weeks overstay. Do you have more info on what happened and what type of interview?
