This checklist is informational, not legal advice. Border officers decide admission. Verify official CBP, CBSA, State Department, Travel.gc.ca, INM, embassy, and consulate pages before travel.
U.S. citizens returning to the United States by land or sea need a WHTI-compliant document. CBP lists U.S. passport book or card, enhanced driver's license, enhanced tribal card, trusted traveler cards, and some official-travel documents.
U.S. citizens entering Mexico by land should carry a passport book or passport card. State Department guidance says travelers to Mexico should review FMM or entry-permit handling with INM before the trip.
Canadian citizens entering the United States by land or water should verify accepted WHTI documents. Mexican citizens entering the United States generally need a passport with visa or Border Crossing Card that fits the trip.
SENTRI, NEXUS, and Ready Lane only help when every traveler and the vehicle fit the lane rules. If one person lacks the right card, use a regular lane and keep documents ready.
U.S. citizen document keywords
For search intent around U.S. citizens crossing by land, keep three phrases separate: passport book, passport card, and WHTI-compliant document. A passport card can help on land and sea, but it does not replace a passport book for international air travel.
Use this with the U.S.-to-Mexico and U.S.-to-Canada guides when planning a specific direction.
Mexico entry and FMM checklist
For Mexico-bound trips, check whether the route needs FMM or other entry-permit handling before joining the line. INM says passport-card use is limited to land border crossings and the border zone.
Pair this checklist with current San Ysidro, Otay Mesa, Tecate, Calexico, Laredo, Hidalgo, Pharr, or Brownsville waits before choosing a crossing.
Canada entry and return documents
For Canada-bound trips, verify identity and citizenship documents, minor travel letters, NEXUS rules, and return-to-U.S. documents together. Canada and the United States each have separate checks.
Pair this checklist with Canada border wait pages when comparing Peace Bridge, Rainbow Bridge, Ambassador Bridge, Blue Water Bridge, Blaine Peace Arch, Pacific Highway, and Sumas.
