U.S. Southern Border
Texas State Troopers help a migrant man and his son to shore after they illegally crossed the Rio Grande River via raft in Roma, Texas. U.S. Southern Border. April 2021. With over 2 million migrant encounters, 2021 was a record year for U.S. Border Patrol encounters at the southern U.S. border. Migrants cross over rivers, by land around fences, and continue as far north as they can. While some may make it, many do not.
