How do I get across the border without a passport?
<|assistant|>
Depending on the border crossing, you may be able to cross the border without a passport if you are a U.S. or Canadian citizen, as these countries share a border. When arriving into the United States from Canada, you may be able to present proof of Canadian citizenship such as a birth certificate, a Canadian passport, or a certified copy of a Canadian birth certificate to a border officer. When arriving into Canada from the U.S., you may be able to present proof of U.S. citizenship such as a birth certificate, U.S. passport, or an unexpired U.S. visa.
