  Lower costs of transportation, communication and information has facilitated illegal immigration. Mexican nationals, in particular, have a very low financial cost of immigration and can easily cross the border. Even if it requires more than one attempt, they have a very low probability of being detected and then deported once they have entered the country. A 2016 research paper published in the American Journal of Sociology hypothesized that border militarization, which took place between 1986 and 2008, in the United States had the unintended consequence of increasing illegal immigration to the United States, as temporary illegal immigrants who entered the United States seasonally for work opted to stay permanently in the United States and bring their families once it became harder to move across the border regularly.
