What state borders Mexico?

The state that borders Mexico is Texas. This is correct because Texas shares a long and significant border with Mexico, extending approximately 1,254 miles along the Rio Grande River. This border facilitates trade, cultural exchange, and migration, making Texas a key state in terms of its relationship with Mexico.

While California and Arizona also share borders with Mexico, Texas has historically had the longest border with Mexico, which influences economic, social, and political dynamics in the region. Florida, on the other hand, does not share any border with Mexico, as it is located on the southeastern tip of the United States, bordered by the Atlantic Ocean and the Gulf of Mexico instead.
