How long an asylum seeker can be detained during a claim differs across the UK, US, Canada and the EU. It complements our earlier detention article with fresh focus on release routes, bail applications, and jurisdictional differences in detention duration limits.[1]
Immigration detention of asylum seekers is one of the most controversial features of asylum systems. UK has no statutory time limit; US applies Zadvydas 6-month presumption; Canada has structured detention reviews; EU has 6-18 month cap. Practice varies substantially.

Legal Framework
UK — Immigration Act 1971 Schedule 2; Immigration Act 2016. US — INA 236, 241; 8 CFR 236, 241; Zadvydas v Davis 533 US 678 (2001). Canada — IRPA Sections 55-61. EU — Returns Directive 2008/115/EC; Reception Conditions Directive 2013/33/EU.
UK Detention
UK is notable for having no statutory time limit on immigration detention. Judicial review is primary check.[2]
Hardial Singh Principles
Hardial Singh v Governor of Durham Prison [1984] 1 WLR 704 established framework:
- Detention must be for the purpose of removal.
- Period must be reasonable in all circumstances.
- Detention should cease if removal not possible within reasonable time.
- Removal pursued diligently and expeditiously.
UK Statistics
~25,000 enter detention annually. Average duration ~30 days. ~2% detained beyond 6 months. IRC facilities — Colnbrook, Harmondsworth, Brook House, Tinsley House, Dungavel, Morton Hall, Derwentside.
Bail from UK Detention
Bail applications to First-tier Tribunal IAC. Considerations — suretys, addresses, reporting, electronic monitoring. Bail for Immigration Detainees (BID) supports.[3]
US Detention
US immigration detention under INA 236 (during removal proceedings) and INA 241 (post-order).[4]
Zadvydas Framework
Zadvydas v Davis 533 US 678 (2001) — post-order detention presumptively unlawful beyond 6 months where removal not reasonably foreseeable.
US Statistics
Daily ICE population ~30,000. ~300,000 book-ins/year. Median duration ~40 days. Some detained for years.
Bond Hearings
Non-mandatory-detention individuals may seek bond before Immigration Judge. Factors — flight risk, danger, family ties, employment. Rodriguez v Robbins 715 F.3d 1127 (9th Cir 2013) supported prolonged detention bond hearings; subsequent case law more restrictive.[5]
Canada Detention
Canadian detention under IRPA Sections 55-61. Grounds — flight risk, identity uncertainty, danger, national security. IRB Immigration Division reviews at 48 hours, 7 days, 30 days.[6]
~4,000 placements annually. Median ~20 days. Small proportion beyond 3 months.
EU Detention
EU Returns Directive 2008/115/EC Article 15 — 6-month maximum, extendable to 18 months in specific circumstances. Reception Conditions Directive addresses asylum applicant detention specifically.[7]
Asylum Seekers Specifically
UNHCR Detention Guidelines (2012) principles:[8]
Presumption against detention. Necessity, proportionality, non-discrimination. Alternatives to detention — reporting, sureties, electronic monitoring. Judicial review access. Vulnerable persons — children, pregnant women, torture survivors — should not be detained. Time limits reasonable and defined.
Vulnerable Detainees
| Category | Framework |
|---|---|
| Torture survivors | UK Adults at Risk; presumptive release |
| Children | UK ended routine 2010; US family detention controversial |
| Pregnant women | UK limited to 72 hours (Immigration Act 2016) |
| Mental health conditions | Medical Justice documentation |
| Trafficking victims | NRM referral triggers protection |
| Age-disputed young people | Presumptive treatment as children |
Routes to Release
- Bail applications — FtT (UK), Immigration Judge (US).
- Habeas corpus — for unlawful detention.
- Judicial review — challenging detention decision.
- Adults at Risk policy application (UK).
- Case progress — asylum grant terminates detention.
- Removal to third country — where removal not to home country.
Support Organisations
UK — BID (biduk.org), Detention Action (detentionaction.org.uk), Medical Justice. US — Freedom for Immigrants, American Immigration Council, Florence Project (AZ), CAIR DC. Canada — CARL (Canadian Association of Refugee Lawyers).
Immigration detention is at the sharp edge of asylum systems. UK has no statutory limit; US has 6-month Zadvydas presumption; Canada has structured reviews; EU 6-18 month cap. Reality remains harsh across jurisdictions. Bail, habeas corpus, judicial review, and vulnerability policies provide release routes.
UNHCR Detention Guidelines (2012)
Conclusion
Rules on detention asylum process vary dramatically. UK — no statutory limit, Hardial Singh reasonableness. US — INA 236/241, Zadvydas 6-month presumption. Canada — structured reviews. EU — 6-18 month cap. Bail, habeas corpus, JR, vulnerability policies provide release routes. See our companion earlier detention article, rights while waiting article, and free legal help article.
