What documents does co-sponsor need? Help GREATLY appreciated!

[FherJess 15]

So as we're awaiting our petition's arrival at the NVC, I'm compiling all the necessary documents for the next phase.

My mother has agreed to be our co-sponsor, she's a NATURALIZED CITIZEN.

Problem is she CAN'T find that certificate.

For the I-134, do they NEED a copy of that certificate to go along with it?

If I'm not mistaken (please correct me if I'm wrong), the actual form she fills out ask for the certificate #.

We are freaking out because a replacement certificate costs $340 and could take up to 6 months.

My fiancé will be going through the Ciudad Juarez consulate in Mexico.

Thanks for any help!!

Copies of US passport is also proof of citizenship if she can provide that. If so then leave the certificate # ( blank )

Thanks for replying!

She doesn't have a passport

And of she leaves the naturalization/certificate # blank, would that cause a red flag or problem?

Hope she can find it.

Hope she can find it.

Thanks! As a back up in case she doesn't find it, my brother has agreed to co sponsor.
