Affidavit of Support Forms and Notary Steps

An affidavit of support is a formal promise by a sponsor to support a newcomer financially. It is part of larger immigration filings, and mistakes can cause delays. A notary is not an immigration advisor, but can handle the sworn signature when needed.

Quick answer. Some affidavit of support forms are signed under penalty of perjury and do not require a notary, while other versions may ask for one. Check the instructions printed on the form you are using; a notary is not an immigration advisor.
