Some asylum seekers are detained during their case. This means the government holds them in a secure facility while their claim is processed. Understanding the detention asylum process is important for anyone seeking protection. This guide explains how long you can be detained in the UK and the US, what your rights are, and how to challenge your detention.[1]

Detention is stressful and frightening. However, knowing the rules can help you protect yourself. Moreover, there are legal ways to challenge detention and get released. This article covers everything you need to know about immigration detention during the asylum process. For more information about the asylum system, see our asylum guide.

UK Detention: Immigration Removal Centres

In the United Kingdom, immigration detention takes place in Immigration Removal Centres (IRCs). These are secure facilities run by the Home Office. The UK is unusual because there is no legal time limit on how long someone can be detained. This means the government can hold you for weeks, months, or even years.[2]

However, detention must follow certain legal rules. The most important rules come from the Hardial Singh principles. These are four rules set by UK courts. First, the government can only detain you if it intends to remove you from the country. Second, the government must work to remove you within a reasonable time. Third, detention must not last longer than a reasonable period. Fourth, if it becomes clear that removal is not possible within a reasonable time, the government must release you.[3]

Rule 35 and Adults at Risk

The UK has special protections for vulnerable people in detention. Rule 35 of the Detention Centre Rules 2001 requires doctors to report when a detainee has a health condition that is harmed by detention, has suicidal thoughts, or may be a victim of torture. When a Rule 35 report is made, the Home Office must review the decision to detain.[4]

Additionally, the Adults at Risk policy gives extra protection to vulnerable detainees. This includes people with serious mental health conditions, pregnant women, and torture survivors. Under this policy, the more vulnerable you are, the stronger the reasons must be for keeping you in detention. Despite these rules, many vulnerable people are still detained. Organisations like Freedom from Torture have criticised the government for this.

US Detention: ICE Facilities and Bond Hearings

In the United States, immigration detention is managed by Immigration and Customs Enforcement (ICE). ICE operates detention centres across the country and also uses private prisons and local jails. The detention asylum process in the US depends on how you entered the country and the stage of your case.[5]

Some asylum seekers face "mandatory detention." This means the government must hold them by law. Mandatory detention usually applies if you entered the US without documents and were caught at or near the border. In these cases, you may go through a "credible fear interview" while in detention. This is a short screening where an asylum officer decides if your fear of persecution is real enough to move forward with a full asylum case.

If you pass the credible fear interview, you may be eligible for release. You can ask for a bond hearing before an immigration judge. At the bond hearing, the judge decides if you can be released and how much money (bond) you must pay. Bond amounts typically range from $1,500 to $25,000. If you cannot pay the bond, you stay in detention. Furthermore, the average time spent in ICE detention has been increasing in recent years.[6]

The Flores Settlement and Children

The Flores Settlement Agreement is an important rule that protects children in US immigration detention. Under Flores, the government must release children from detention as quickly as possible, usually within 20 days. Children must be held in the least restrictive setting possible. Moreover, detention facilities for children must meet certain standards for food, water, medical care, and safety. This settlement has been a key protection for unaccompanied minors and families with children.[7]

Detention Rules: UK vs US Comparison

Your Rights in Detention During the Asylum Process

Even if you are detained, you still have important rights. These rights apply in both the UK and the US. First, you have the right to access a lawyer. In the UK, you can get legal aid to pay for a lawyer. In the US, you have the right to a lawyer, but the government does not pay for one. Many organisations offer free legal help to detained asylum seekers.[8]

Second, you have the right to medical care. Detention centres must provide healthcare, including mental health support. Third, you can contact your family. You have the right to make phone calls and receive visits. Fourth, you can continue your asylum claim from detention. Being detained does not stop your case. You can still attend hearings, submit evidence, and work with your lawyer.

Detention must be used only as a last resort, and for the shortest appropriate period of time.

How to Challenge Detention

In the United Kingdom: Bail Applications

In the UK, you can apply for bail at any time during your detention. You apply to the First-tier Tribunal (Immigration and Asylum Chamber). At the bail hearing, a judge decides if you should be released. The judge considers whether you are a flight risk (likely to run away), whether you have a fixed address, and whether there are good reasons to keep you detained.[9]

If bail is granted, you will usually have conditions. These may include living at a specific address, reporting to the Home Office regularly, and wearing an electronic tag. You can also challenge your detention through judicial review. This is a legal process where a court checks whether the government acted lawfully. A lawyer specialising in immigration law can help with this. You can find one through our expert directory.

In the United States: Bond Hearings

In the US, you can request a bond hearing before an immigration judge. At the hearing, you must show that you are not a danger to the community and not a flight risk. If the judge agrees, they will set a bond amount. You or your family must pay this amount to get released. Additionally, some detainees can challenge their detention through habeas corpus petitions in federal court. This asks a judge to review whether the detention is legal.[10]

Alternatives to Detention

Both the UK and the US have alternatives to keeping asylum seekers in detention. These alternatives are cheaper and less harmful. In the UK, alternatives include regular reporting to the Home Office, electronic monitoring (GPS ankle tags), and community support programs. Organisations such as UNHCR have argued that alternatives to detention are more effective and more humane.

In the US, alternatives include the Intensive Supervision Appearance Program (ISAP), which uses electronic ankle monitors and regular check-ins. Community-based programs, where non-profit organisations help asylum seekers attend their hearings, have shown very high appearance rates. Studies show that over 90% of asylum seekers on community programs attend all their court dates. This suggests that detention is often unnecessary.[11]

Furthermore, alternatives to detention are much cheaper. Detaining one person in the US costs around $150 per day. Community supervision costs around $5 per day. For the UK, the average cost of detention is around $100 per day, while reporting conditions cost a fraction of that. Consequently, many experts argue that governments should use alternatives much more often. To learn more about the asylum process and your options, visit our asylum guide.

Conclusion

The detention asylum process affects thousands of people every year in the UK and the US. In the UK, there is no time limit on detention, but it must be for a reasonable period. In the US, some asylum seekers face mandatory detention, but bond hearings offer a path to release. Regardless of where you are detained, you have rights. You can access a lawyer, receive medical care, and continue your asylum case. If you are vulnerable, special protections should apply. Alternatives to detention exist and are effective. If you or someone you know is detained, seek legal help immediately. Understanding your rights is the first step to protecting them.
