Which state is known for bordering Mexico?

California is known for bordering Mexico due to its extensive southern border, which runs alongside Mexico for approximately 140 miles. This border has significant implications for immigration, trade, and cultural exchanges between the two regions. California's proximity to Mexico also means that it is a focal point for various immigration policies and practices, as well as a hub for both legal and undocumented crossings. The state's demographics and economic ties to Mexico further emphasize its importance in discussions related to immigration and border issues.

The other states listed—Oregon, Wyoming, and Montana—do not share a border with Mexico. Oregon is located to the north of California and is bordered by the Pacific Ocean to the west and the state of Idaho to the east. Wyoming is situated to the north of Colorado and is more centrally located within the United States, while Montana lies further north and is bordered by Canada to the north, making them irrelevant in the context of bordering Mexico.
