|Illegal immigration refers to the migration of people across national borders in a way that violates the immigration laws of the destined country. Illegal immigration is overwhelmingly upward, from a poorer to a richer country., and one measurable factor is the ‘push-pull’ incentive – the quality of life in the host country against the home country. When potential immigrants believe that the chances of successfully migrating upwards are greater than the risks/costs, illegal immigration becomes an option. The benefits taken into account include not only expected improvements in income and living conditions, but also expectations in relation to potential future residential permits, where illegal immigrants are given a path to naturalization or citizenship. The costs may include restrictions on living as an illegal immigrant in the destination country, leaving family and ways of life behind, and the probability of being detained and resulting sanctions.|
