In Minnesota, a person who wants to be a notary, also called a “notary public,” has to be at least 18 years old and has to be a Minnesota resident. A notary does not have to be a US citizen, but must be in the country legally.
If they meet these requirements, they apply and pay an application fee. Minnesota does not require any special classes or training but classes are available for anyone who wants to take them. Once the Office of the Secretary of State accepts the application, the person is a notary. The notary has to buy their own official stamp and anything else they may need.
