Four bridges in El Paso make it easy to cross into Mexico. U.S. Canadian citizens are not required to show papers when crossing the international boundary into Juarez, provided their stay is less than 72 hours and they do not travel beyond the 18-mile limit. Non-citizens must carry a valid passport or alien registration card. Visitors who require a U.S. visa must be in possession of and present their passport with the remark "multiple entry visa," issued by U.S. authorities, together with the entry card received upon first entry into the U.S. Pedestrians pay 25 cents to cross into Juarez and a little more to return (based on the peso exchange rate); vehicles pay a nominal fee each way (except at the Bridge of the Americas, which is free).

Once every 31 days, U.S. residents may bring back duty free articles for personal or household use up to $400 in value, one quart of liquor per person over 21 years of age, and either one carton of cigarettes or 100 cigars (non-Cuban). Do not bring back live animals or birds, potted plants, lemons, apples, mangos, some herb teas, pork, ham, uncooked chicken, eggs or products made from endangered species. Before crossing, request information about which agricultural products you may bring back from Mexico. Call 915-633-7300.
