In 1920, Mexicans entering the United States primarily needed to have a valid passport and, in many cases, a visa. However, during this period, Immigration policies were relatively lenient, and many Mexicans crossed the border without formal documentation, especially due to labor demand in the U.S. following World War I. Additionally, the 1920s saw the establishment of the Border Patrol, which began to enforce stricter immigration controls.
80000
cuz they can
Yes - the Northern Hemisphere security initiative means even Americans need a passport To enter the US. Puerto Ricans, Canadians and Mexicans all do so too.
Most estimates are that about 890,000 Mexicans immigrated to the US in the period 1910-1920.
That's hard to say since several parts of the US belonged to Mexico at one point. And lets not forget the when the states where in need of extra hands they let the Mexicans enter and then they would kick them out but they let them enter again. So it's difficult to say.
Sure, if they intend to go on vacation and then return to Mexico. However, to enter US territory, they need a passport and a Visa, which sometimes is difficult to obtain.
Both or none, depending on your point of view. It is a demographic and economic event which has been politicized (i.e: Mexicans came into the US an then someone noticed), not the other way around (i.e: someone gave Mexicans permission to enter US territory).
Yes, Mexico is a foreign country.

You only need a valid passport to enter Mexico.

Because the Mexicans are faking to be nice so the US thinks they are friends.
