However, illegal migration does come with a lot of negatives as well. To illegally migrate to a country, people often have to rely on human smugglers and other sketchy methods to enter it. They stuff people into ships and other vessels in an attempt to smuggle people. These ships, trucks and vessels often end up in accidents and cause deaths. Since 1996, over 80,000 illegal immigrants have died from such accidents or at detention camps. The majority of such deaths are unrecorded and are not officially accounted for. The immigrants are usually in debt to the smugglers and spend months or even years trying to pay the debt back. Once settled, they send words of a good life and employment which then encourages more people from their homelands to migrate to other countries. Another threat is to the National Security of a place. Terrorists usually enter the country illegally through the same routes that illegal immigrants take. Illegal immigration, interception of these immigrants and further legal processes to deport them from the country costs the countries a lot of money too. In the US alone, it costs them a whopping net (costs of services received – tax contributions) of $ 54 billion each year. This might be higher in countries like India which has the highest illegal immigration numbers. Due to easily available immigrant low-skilled labour, the per capita income of native low-skilled labour also decreased causing financial problems to the native population.
