Can I cross into US from Canada when my passport is being renewed?

If your passport is being renewed, you generally cannot cross into the U.S. from Canada without it. The U.S. requires a valid passport for entry, and other forms of identification may not be accepted. If you have a passport renewal receipt, it may not suffice for entry, so it's best to wait until your passport is renewed or check with U.S. Customs and Border Protection for specific alternatives.
