Marriage Certificate & SSN

I have a couple of questions on the list of sponsor documents. Someone please help!

1 Do I need to provide a copy of marriage certificate?
2. Do I need to provide a copy of SSN?

No need to provide copy of SSN as it will be on yr tax returns.

Porvide original marraige certificate with yr relatives.
Show only when asked to do so.
Do not give original to embassy staff
