The objective of enforcement is to maintain the integrity of a State’s immigration laws. Border officials are tasked with detecting breaches of immigration laws and procedures and with dealing with them appropriately. Border officials use enforcement tools, including deportation or removal, to encourage compliance. At points of entry (POE), border officials are primarily responsible for processing the entry and exit of people and goods, as well as for preventing transnational organized crime such as smuggling of migrants and trafficking in persons, referring those in need of international protection and detecting irregular migration.
In some instances, border officials at POE might encounter migrants who are attempting to enter a country without appropriate documentation. Non-nationals who enter or stay in a country may be undocumented migrants for several reasons: they may lack an identity document that proves their right to enter and stay in another country; their document may be fraudulent; their visa may have expired; they may have breached a condition of the visa. In such cases, a migrant who is found in breach of immigration laws or whose admission into the State is considered contrary to the provisions of relevant acts or regulations, and who has not otherwise demonstrated an entitlement to remain, is liable to be ordered to leave the territory, or be deported or removed.
It is important to note, however, that even when in an irregular situation, migrants are still entitled to the respect, protection and fulfilment of their human rights. Moreover, as per the 1951 Convention, refugees are to be granted access to international protection against being penalized for unauthorized entry or stay if they have travelled from a place where they were at risk. Other categories of migrants, too, such as victims of trafficking in persons, unaccompanied children and other vulnerable groups might be unable to obtain identity documents to support their claims and have other no choice than to use irregular pathways.
