Proof of American citizenship for interview

[A.M.E 1]

Hi, everybody.

My future mother-in-law (co-sponsor) lost her birth certificate. Can she scan her passport as proof of citizenship for my interview? Furthermore, can she scan only the biographical page or will she need to scan all the pages of her passport?
Oh, one more question: A friend of mine is sort of going through the same thing, except that her co-sponsor not only lost his BC, his passport expired a while ago. Along with the copy of his passport, he scanned his driver's license and his SSC. Can those be helpful in anyway?

Thanks in advance.

Passport biographical page is fine

Ok, thank you.
But do you know if this friend of mine can have any trouble with her co-sponsor's expired passport?

Congrats on the American citizenship, by the way.

Even expired is should be ok (however there is no clear distinction written by uscis that stipulates the passport need to be current) however, if you wanted to err n the safe side, nowadays it is super easy to order a copy of a birth certificate online from the state records... Took me $8 and 3 weeks...
