Name one state that borders Mexico.

Four US states share a border with MEXICO along the southern border of the United States: CALIFORNIA (southwestern corner — San Diego is near the border); ARIZONA; NEW MEXICO; TEXAS (the longest US-Mexico border segment, including El Paso, Laredo, and Brownsville). The USCIS Civics Question 91 asks to name one state that borders Mexico — any one of these four is correct. Mexico is one of two countries that share a land border with the United States (the other being Canada to the north). The US-Mexico border is approximately 1,954 miles long. Other geography questions in the USCIS civics test: The Pacific Ocean is on the West Coast (California, Oregon, Washington, Alaska, Hawaii); the Atlantic Ocean is on the East Coast; Canada shares the northern border; rivers including the Rio Grande form part of the US-Mexico border.
