Joint Sponsor last name doesnt match birth cert

[OntarioMan 9]

Well as the title states we have all of the joint sponsor information we need to send it out but we are worried about the last name being different from birth certificate from all of the other documents. They also don't have a passport just a birth certificate. Am I overthinking this?

I do not see an issue.

Most women change their last name upon marriage. So, of course, the last name would be different than BC.

Jul 25, 2021 — Other Names. Most USCIS forms also ask if you have used other names. You will need to enter your maiden name and any other versions of your name ...

On the i864 for a joint sponsor it doesnt have that option available

Oh good. Im just a little nervous because I know it doesnt ask for a marriage certificate at all in the instructions but I am so scared of being denied

You can submit MC with it. No problem.

When you upload a document you don’t have an space to add some notes? For the CR1 visa I had. Or see if you can add any other document (apart of the ones requested) so you can add any other proof like the marriage certificate per example
