Remember that half the territory of the EUA was Mexican territory until the war with México in 1846, the states of Texas, Arizona, New México, California). so you have a lot of families with ties with México. until second half of the 20th century, moving from one country to the other was easy.
a "better life" MEXICANS (:
Mexicans may immigrate to the US for various reasons, including seeking better job opportunities, reuniting with family members, fleeing violence or political instability, or pursuing higher education. Economic factors, such as higher wages and stronger job markets, also play a significant role in driving Mexican immigration to the US.
Mexicans
They immigrate because they wanted to find jobs to support their families.
because they wanted to restart their life. Also because of jobs they maybe had a family over there
Mexicans. Apex :)
Since the late half of the 20th century.
People immigrate to Mexico from all over the world. Most people who immigrate to Mexico come from the US. Reasons for coming to Mexico often include lower health care costs, warmer climate, and generally a more relaxed lifestyle.
I personally know some First Nations people and asked this. They said they do not need to immigrate as they consider themselves part of both USA and Canada.
A push factor is a better life a pull factor is better jobs
