Can I just notarize one affidavit and print copies?

You should notarize at least 5 originals of the Affidavit of Citizenship Evidence because you’ll need them for your passport application and IRS notice, and it’s a good idea to keep at least one for your files. Additionally, having multiple notarized copies allows you to send notices as needed.

It’s best to have original notarized versions for most situations.
