Maitrayee Guha asked: To what extant is Illegal Immigration a Security Issue?

Namrata Goswami replies: To the extent that illegal immigration threatens to overshadow the population of a particular state. For instance, illegal immigration has threatened to change the demography of states in India and several other states in the world, so much so that there is a pervasive fear in these societies that the states' ethnic composition will change in favour of the migrant . Additionally, illegal immigration becomes a security issue when their names are added to a country's voter list. Linkages found between illegal immigrants and underground gangs, terrorist organisations and insurgent groups are also of serious security concern. Worse of all, since immigration is illegal, it is difficult to trace their networks and secret locations in order to bring the guilty to justice.
