Definition

In plain language

Many countries require foreigners to register with the authorities and follow rules on where they live and how long they stay. This lets the State know who is on its territory.

Academic definition

International law gives States broad discretion over entry and residence of aliens, but limits how that control is exercised. The International Covenant on Civil and Political Rights protects the liberty of movement of aliens lawfully present (Article 12) and sets procedural guarantees before expulsion (Article 13), and consular access rights under Article 36 of the Vienna Convention on Consular Relations apply to detained foreigners. Registration and control measures are mostly domestic, so the rules vary widely and are tested for proportionality and non-discrimination.

Context

Legal effect: Context-Dependent

Scope

Covers administrative registration, identity checks and monitoring of non-nationals; expulsion, asylum and refugee status determination are treated in other records.

Legal context

No treaty prescribes a registration system; ICCPR Articles 12, 13 and 26 and Article 27 of the 1951 Refugee Convention on identity papers set limits. The ILC's 2014 Draft Articles on the Expulsion of Aliens address procedural protections on removal.

Diplomatic context

Embassies often register their nationals with host authorities and treaties on residence, visas or labour often include registration requirements; mass registration drives can cause diplomatic friction.

Institutional context

Carried out by national immigration and interior ministries, with oversight from human rights treaty bodies and UNHCR for refugees.

Historical context

Modern alien registration systems developed in the nineteenth and twentieth centuries with passports and immigration control, and many States adopted general registers during wartime.

Why it matters

Registration decides access to residence rights, work and services, and gaps can leave people in an irregular status exposed to detention or expulsion.

Usage

Register: Legal

Usage note

'Alien' is the traditional legal term; many national laws and UN texts now prefer 'non-national' or 'foreign national'.

Example

New residents must complete alien registration within thirty days of arriving in the country.

Example scenario

A worker from State B moves to State A and must register with the local immigration office within a fixed period. The registration allows State A to track residence permits, while the worker's embassy is notified if he is later detained.

Common misuse

Treating registration requirements as a ground to deny basic rights; registration is an administrative duty, not a loss of human rights protections.

Not to be confused with

  • Expulsion of aliens
  • Refugee status determination
  • Visa requirement
