The Border Patrol reported 608,037 encounters with Mexican nationals in 2021, accounting for 37% of the total. The remaining 1,051,169 encounters, or 63%, involved people from countries other than Mexico – by far the highest total for non-Mexican nationals in CBP records dating back to 2000.

Proponents argue that too many immigrants cross our border every year and anyone entering the U.S. from a foreign country should pass through customs and have a valid visa. Opponents of stronger border controls argue the majority of illegal entrants are migrants seeking temporary work and pose no threat to national security.
