One of the main reasons for illegal immigration is economy, poverty, and unemployment. Those issues happen because of the politics negligence. For this reason, people have to travel undocumented to other countries, for example US. However, many of them died because of the crime and corruption in Mexico. To start with, the drug smugglers are participating in human trafficking, and one of the groups at most risk to be kidnapped is people who go through Mexico to get to the US. It isn't uncommon for people trying to immigrate illegally to go missing trying to get to the US. Recently, seventy-two illegal immigrants from Central and South America trying to get to the US were found dead. It is suspected they were killed for refusing to do work for drug traffickers. Lately, there's been a decline on illegal immigration because there are different governments in Latin America, and the economy is improving as more job opportunities and increase in wages have resulted in those who would be willing to immigrate illegally to stay home. Most who immigrate illegally would rather stay at home and work than to take a risky journey into the US and be away for long periods of time. Additionally, Bush and Obama have deported approximately three million immigrants and have created a tremendous deficit. That means lower job opportunities. Therefore, it is more sensible to stay at home and work. To end with, illegal immigration is influenced by many factors. It is influenced by poorly management of the economy. As if USA economy is doing well and the rest of countries, Central or South America economy is doing bad, then there is more incentive to immigrate to the US plus the cost of actually getting into the US since it has risen quite a bit. Another factor is safety, as the trip to US is fairly dangerous especially those who are traveling through Mexico have to deal with drug cartels. Another large influence is crime, as it becomes increasingly more dangerous to get to the US through Mexico because of drug cartels. So many potential illegal immigrants are deterred by the risk of being knapped or killed.
