The United States shares a lengthy border with Mexico, and there are four states that directly touch this international boundary. These states are:
- California
- Arizona
- New Mexico
- Texas
California is located on the west coast, bordered by the Pacific Ocean to the west and Mexico to the south. Arizona follows, with its southern border entirely along the Mexico line. Next is New Mexico, which shares a portion of its border with Mexico. Lastly, Texas has the longest border with Mexico, stretching over 1,200 miles and featuring numerous border towns and crossings.
Each of these states has a unique culture shaped by the proximity to Mexico, and they play a significant role in trade, tourism, and migration between the two countries.
