Documents for Evidence of U.S. Citizenship

[ral]

Hi,

My wife is a US citizen and we are preparing documents and forms to file for my marriage-based green card. She naturalized through her parents when she was a kid (hence, she did not get a naturalization certificate), so the only proof we have of her US citizenship is her US Passport. Would this be enough or do we need to get additional evidence? If so what would that be?

Yes, her valid US passport is enough.
