Documents for derivatives?

[pm5k 129]

For a US Citizen sponsoring a sibling, the instructions are fairly simple in my understanding (supply a birth certificate for the USC, and birth certificate for the beneficiary, showing a common parent)

If the beneficiary is married and has children, do supporting documents for them need to be sent as well (such as birth certificates, marriage certificate, etc)?

Thanks!

Supporting documents for derivative beneficiaries are not sent in with the I-130. Nothing is needed from the derivative beneficiaries until the NVC stage and the PD is almost current.

hi

for the i130 only the documents showing the relationship between siblings

it is at the NVC stage where the beneficiary and derivatives will have to send all the rest of documents
