Construction of physical barriers: Some countries, such as the United States and Mexico, constructed physical barriers along their borders to deter undocumented immigration. These barriers made it more difficult for people to cross the border illegally, but they also had the unintended consequence of separating families and communities.
Crackdowns on undocumented immigrants: Many countries began cracking down on undocumented immigrants, making it more difficult for them to obtain legal status or work permits. This made it more difficult for undocumented immigrants to stay in the country and forced many of them to return to their home countries.
Changes in visa requirements: Some countries, such as the United States, changed their visa requirements, making it more difficult for people from certain countries to obtain visas to enter the country. This made it more difficult for people to come to the country for work or study, and it also separated families and communities.
Anti-immigrant sentiment: In some countries, there was a rise in anti-immigrant sentiment, which led to discrimination and violence against undocumented immigrants. This made it more difficult for undocumented immigrants to live in the country and forced many of them to return to their home countries.
The combination of these factors made it more difficult for undocumented immigrants to enter and remain in the United States and other countries, which led to a decline in Latino immigration in the late 2000s.
