Some asylum seekers are detained during their case. Detention means being held in a closed centre, not free to leave. This is one of the hardest parts of the asylum process. The rules are different in the UK and the US. In both countries, detention should not be used unless it is needed. This guide explains how long you can be detained, your rights inside, and how to challenge detention. The information is based on official rules and key court decisions.[1]

Detention is not a punishment. It is meant to be used only for immigration purposes, such as making sure you attend hearings or arranging removal. However, in practice, many asylum seekers spend weeks or months in detention. Knowing the rules helps you protect your rights. This asylum guide covers what every detained applicant should know.

UK Detention: Immigration Removal Centres

In the UK, immigration detention happens in places called Immigration Removal Centres (IRCs). These are run by private companies for the Home Office. There are also short-term holding facilities at airports and some prisons used for immigration detention. People may be detained at any stage of the asylum process, but most are detained near the end, when removal is being arranged.[2]

The Hardial Singh Principles

The UK does not have a fixed legal time limit on immigration detention. However, the courts have set important rules called the Hardial Singh principles. These come from a famous 1984 court case. They say:

• The Home Office can only detain for an immigration purpose, such as removal
• The period of detention must be reasonable in all the circumstances
• If removal cannot be done in a reasonable time, detention must end
• The Home Office must act with reasonable speed to arrange removal

If detention breaks any of these rules, it becomes unlawful. You can apply to a court for release and may be entitled to compensation.

Bail Applications

You can apply for "immigration bail" at any time. Bail means being released on conditions, such as living at a set address or reporting to immigration officials. Bail is usually decided by the First-tier Tribunal. Many detained people get released on bail, especially with a good lawyer.

Rule 35 and the Adults at Risk Policy

Rule 35 of the Detention Centre Rules 2001 protects vulnerable people. A doctor in the IRC must report concerns about anyone who:

• May be a victim of torture
• Has health problems made worse by detention
• May be at risk of suicide

The Home Office must then review the detention. The Adults at Risk policy adds extra protections for people with serious vulnerabilities, including survivors of torture and trafficking.

US Detention: ICE Custody and Bond

In the US, immigration detention is run by Immigration and Customs Enforcement (ICE). People are held in ICE detention centres or in county jails contracted by ICE. Detention can last from a few days to several years, depending on the case.[3]

Mandatory Detention

Some asylum seekers are subject to "mandatory detention" under section 235 or 236(c) of the Immigration and Nationality Act. This means an immigration judge cannot release them on bond. This applies to people who arrive at the border without papers, those with certain criminal convictions, and those in expedited removal.

Credible Fear and Reasonable Fear Interviews

If you are detained at the border and want asylum, you should ask for a "credible fear" interview. An asylum officer will check if you have a real fear of persecution. If you pass, you can continue your case from inside detention or sometimes be released. If you fail, you can ask an immigration judge to review the decision. For full details, see the official USCIS guidance.

Bond Hearings

If you are not subject to mandatory detention, you can ask for a bond hearing. An immigration judge decides if you can be released and how much bond you must pay. The judge looks at:

• Whether you are a flight risk (likely to miss future hearings)
• Whether you are a danger to the community
• Family ties and community support in the US

Bond amounts often range from $1,500 to $25,000 or more. Once paid, you are released and can continue your case from outside detention.

Flores Settlement

Children in detention are protected by the Flores Settlement Agreement of 1997. This sets standards for the care of children, including limits on how long unaccompanied children can be held. Generally, children should not be held in standard immigration detention for long periods.

How Long Are People Detained?

Detention Rules: UK vs US

Your Rights in Detention

Even in detention, you have important rights. These rights protect your access to your case and your basic well-being.[4]

Right to a Lawyer

In the UK, you have the right to free legal advice through the Detention Duty Advice Scheme. A solicitor visits the IRC to give first-time advice. In the US, you have the right to a lawyer at your own expense. There is no government-funded lawyer in immigration court, but free legal aid groups serve some detention centres.

Medical Care

Detention centres must provide basic healthcare. This includes a doctor, nurses, and access to mental health services. If you have a serious health problem, ask to see medical staff and request a Rule 35 report (UK) or a parole request (US).

Family Contact

You have the right to contact your family. This includes phone calls and visits. Visits are usually allowed several times a week. Phone calls may be limited or expensive. Some centres allow video calls and email.

Continuing Your Case

You can continue your asylum case from inside detention. You can attend hearings (sometimes by video link). You can submit documents and evidence. Detention should not stop your case from going forward, although it makes preparation harder.

How to Challenge Detention

You should not accept detention without challenge. Both systems give you legal tools to fight for release.[5]

UK: Bail Applications

You can apply for immigration bail at any time. Bail applications are usually decided within a few days. Your lawyer will need:

• A bail address (where you will live if released)
• Sometimes a "Financial Condition Supporter" who promises money if you break conditions
• Evidence of why you should be released, such as health, family, or weakness of the removal case

If bail is refused, you can apply again, especially if your situation changes. You can also seek judicial review of unlawful detention. Detailed UK rules are on GOV.UK.

US: Bond Hearings

You can ask for a bond hearing in immigration court. The hearing is normally short, perhaps 30 minutes. You should bring evidence such as:

• Letters of support from family, friends, employers
• Evidence of community ties
• Proof of identity and address
• Evidence that your asylum case is strong

If bond is refused, you can apply again later if your situation changes. You can also use a "habeas corpus" petition to challenge unlawful detention in federal court.

Alternatives to Detention

Both countries have alternatives to detention. These let people stay free while their case continues. Examples:

• Reporting requirements: regular check-ins at an immigration office
• Electronic monitoring: ankle bracelets in the US ("ATD" programs)
• Community sponsorship: living with family members or in supported housing
• Bail with conditions: living at a set address, attending all hearings

Studies show that alternatives to detention are cheaper and just as effective at making sure people attend hearings. The UNHCR has long called for governments to use alternatives instead of detention.

Detention of asylum seekers should be used only as a measure of last resort, when necessary and proportionate, and after alternatives to detention have been considered.

Conclusion

Detention during the asylum process is hard. The rules in the UK and US are different, but both systems give you ways to challenge detention. Use bail applications in the UK or bond hearings in the US. Ask for legal help as soon as possible. Vulnerable people, including survivors of torture, often qualify for release. An expert witness can help by writing a medical or country report that supports your case for release. Most importantly, do not give up. Many detained people win their cases and are released to continue their lives in safety. For broader country information, see our country reports and human rights sections.
