Historically, going into Mexico has not required a passport. However, recent law now states that a passport is required to enter into Mexico or to get back into the United States! It is required that you bring your passport on the trip in case immigration officers on either side of the border asks for it. As they say, “Better to bring it and not need it , than to need it and not have it!!!” If you decide to come on the trip without a passport and you are not allowed to go into Mexico, then you will have to stay behind and find a return trip back home on your own without any refund for the tour.
The border wait ranges greatly depending on season, political climate, day of the week, special events, and many other factors. Many tour providers will lie and tell you they have access to special “fast passes.” These fast passes are easily attainable and because of ease of access are often actually not faster than the Ready Lane. Currently the best lane to use is what’s known as the “Ready Lane” and everyone with a current and valid passport is able to use it. Border wait times can be as fast as 15 mins or as long as 2 hours.
