US citizen applying GC for parents

[applyingforparents]

Will there be an interview like GC based on marriage to US citizen? If there is, what kind of questions will they ask? What to expect at the interview? Thank you very much.

It is not like a USC spouse interview, where their main objective is to make sure the marriage is a genuine one.
Here their main focus would be establishing that they are really the parents of USC who is petitioning for them. They can direct few questions towards
establihing that And most importantly, it would serve best for the USC to
get his/her own original birth certificate with both his parents' correct names
on it and matching with their own bcs and their passports.
