Can I Get ILR with a Complicated Immigration History?

Key Points

• Long residence ILR requires 10 years of continuous, lawful residence. From 11^th  April 2024, absences must not exceed 180 days in any rolling 12-month period; different rules apply to time before that date.
• Criminal convictions can prevent ILR or citizenship, but the outcome depends on the type of offence, the sentence imposed, and how much time has passed. Minor or old matters do not automatically cause refusal.
• A previous ILR or visa refusal does not permanently bar a future application, but it will be scrutinised. The strength of the new application and the reason for the earlier refusal are what count.
• Using false identity or nationality details in a past application is treated very seriously. The Home Office can impose re-entry bans of up to 10 years for deception, but full and honest disclosure of past errors can sometimes be taken into account.
• Pending divorce affects ILR applications on the spouse route, but not long residence claims. If ILR is already held, divorce does not remove it.

You may still be able to apply for ILR or British citizenship even if your history includes absences, a criminal record, a past refusal, a relationship breakdown, or questions about your identity. Whether you can succeed depends on the specific facts of your case and which route you are applying under.

The Home Office assesses each application on its own merits. The questions it asks are not simply whether a problem exists, but what it is, how serious it was, how long ago it happened, and whether the person has been honest about it. A long track record of lawful residence, a genuine private life in the UK, and transparent disclosure can go a long way even where the history is not straightforward.

What follows is a practical breakdown of the main complications people face and what effect each of them actually has. The law is not always as rigid as people fear, and in my experience, getting the right immigration law advice at the right time makes the difference between a refusal and success.

Absences from the UK

The 10-year long residence route to ILR requires continuous lawful residence throughout the qualifying decade. The rules on what counts as “continuous” changed in April 2024. For time spent in the UK before 11 April 2024, total absences across the 10 years must not normally have exceeded 548 days, and no single absence should have been longer than 184 days. For time on or after that date, the test is different: no more than 180 days outside the UK in any rolling 12-month period, with the overall 548-day cap no longer applying to that later portion. The full rules are set out in Appendix Long Residence.

Those limits sound strict, and they are. But they are not absolute. The Home Office can use discretion for genuine exceptional circumstances, such as serious illness, a humanitarian crisis, or travel that was genuinely beyond the applicant’s control. The threshold for exercising that discretion is high, and it should not be relied upon lightly; if your absences are close to or above the limits, getting early legal advice before applying is far safer than hoping for discretion after the fact.

Absences also affect the naturalisation route to British citizenship. For a standard five-year qualifying period, no more than 450 days outside the UK in total are permitted, with no more than 90 days in the final year before the application date. For those applying on the basis of being married to a British citizen, the limit is 270 days across three years. If your absences are high, calculating whether you qualify and when the earliest safe application date falls is something a solicitor can work out from your travel history before you commit to an application.

Criminal Convictions and the Good Character Requirement

Every ILR applicant must satisfy the suitability requirements set out in Part 9 of the Immigration Rules, and every citizenship applicant must meet the good character requirement. Both assessments look at criminal history, and both are unforgiving at the serious end of the scale.

For ILR, the position since March 2026 is that any custodial sentence of 12 months or more leads to mandatory refusal, as does any suspended sentence of 12 months or more. A custodial sentence of less than 12 months will usually also result in refusal. Persistent offending, sexual offences, and drug-related offences with a serious harm element are treated with particular severity. The same framework broadly applies to naturalisation for citizenship.

Below those thresholds, the picture is more nuanced. A caution, a fine, or a non-custodial disposal from several years ago does not automatically end the application. The Home Office looks at the number of offences, their seriousness, the time that has passed, and whether the person has otherwise complied with the law. An isolated minor matter from many years ago, fully disclosed, is treated very differently from a pattern of repeated low-level offending. The critical point is disclosure: failing to mention a conviction or caution, however old or minor, can itself become a ground for refusal on the basis of deception.

Deportation Orders and the Risk of Removal

A deportation order is a formal direction requiring a person to leave the UK and prohibiting their return. Under the Immigration Act 1971, the Home Office must consider making a deportation order where a non-citizen receives a custodial sentence of 12 months or more, or where deportation is considered conducive to the public good. A deportation order, once in force, cancels any existing leave to remain, including ILR.

Where a deportation order is in place or threatened, there is often still a legal argument available. Human rights law, in particular the right to respect for private and family life under Article 8 of the European Convention on Human Rights, can be engaged where a person has deep roots in the UK: long residence, children, employment, and community ties all carry weight. Challenges to deportation decisions are pursued through appeal to the First-tier Tribunal (Immigration and Asylum Chamber). These cases are fact-specific and require careful preparation, but they are not hopeless even where the criminal record is significant.

Long residence itself provides a degree of protection in some cases. The longer and more established a person’s life in the UK, the higher the bar the Home Office must clear before deportation can be justified. That does not remove the risk, but it shapes the argument.

False Identity, Nationality History, and Past Deception

Using a false identity or false nationality in a previous immigration application is one of the most serious issues the Home Office can encounter. Deception in an application carries a mandatory 10-year re-entry ban under the Part Suitability rules, regardless of when the deception took place. Where it involved falsified documents, the consequences can extend to criminal prosecution under the Fraud Act 2006 and the Identity Documents Act 2010.

That said, the position is not always irretrievable. Where a person entered the UK under a false identity but has since lived lawfully for a long period, fully corrected their details, and can demonstrate the circumstances in which the original deception arose, there are cases where a path forward exists. The Home Office has a discretionary power to consider whether a ban should still be applied in subsequent applications for entry clearance, and an applicant can put forward reasons why it should not. These arguments require compelling evidence and are not straightforward, but they are not foreclosed.

The lesson that comes through consistently in these cases is that honesty, even about past dishonesty, produces better outcomes than concealment. If false details were previously used and have since been corrected, full disclosure in any new application, supported by a clear account of what happened and why, gives the best chance of the Home Office taking a proportionate approach. Trying to hide a past that is already on the Home Office’s system is far more likely to cause damage than disclosing it properly.

A Previous Visa or ILR Refusal

A previous refusal does not permanently prevent a further application. What it does do is flag the earlier decision for scrutiny: the Home Office will examine the refusal reason and look to see whether the same problem is present in the new application.

Where the earlier refusal was for a technical reason, such as missing documents, an incomplete form, or a test not yet passed, a fresh and properly prepared application can succeed without difficulty. Where the refusal involved a finding of deception, the position is more serious and the 10-year ban under Part Suitability may apply. Where the refusal was on suitability grounds relating to criminal history or immigration breaches, the new application must show that those grounds no longer apply or that the circumstances have materially changed.

Depending on the route and the nature of the refusal, the options after a refused ILR decision may include an administrative review (which must be requested within 14 days if in the UK, or 28 days if abroad), an appeal to the First-tier Tribunal on human rights or other grounds, a judicial review where the decision was unlawful, or a fresh application once the underlying issues have been resolved. Which of those routes is appropriate turns entirely on why the refusal was made. One of the most important role I have, as an Immigration Law Solicitor is to examine the reason for the ILR application and establish the best way forward in terms of remedies.

Pending Divorce and Relationship Breakdown

Divorce affects ILR applications differently depending on which immigration route is being used. For those on the spouse or partner route, leave to remain depends on the relationship remaining genuine and subsisting. If the relationship ends before ILR is granted, the visa can be curtailed, typically giving 60 days to either apply under a different route or leave the UK. The Home Office must be notified of a separation; failing to do so and continuing to rely on a relationship that has ended creates a serious risk of a later deception finding.

For those applying under the long residence route, divorce is largely irrelevant to the ILR application itself. Long residence does not depend on a current relationship; it depends on 10 years of continuous lawful presence. A person going through a divorce while holding valid leave on a work or study visa is, in immigration terms, in much the same position as before the marriage ended, provided their underlying status is maintained.

Once ILR is already held, divorce has no effect on it. The status does not depend on a relationship. The same applies to British citizenship: if a person holds ILR and then applies for naturalisation, an ongoing or recently concluded divorce does not affect eligibility, though it may affect which qualifying period applies if the application was previously based on being married to a British citizen.

What to Do If Your History Is Complicated

Before making any application for ILR or citizenship where the background is not straightforward, consider the following:

• Get a full picture of your immigration history before applying. A Subject Access Request to the Home Office will produce a record of all previous applications, decisions, and entry and exit data held on your file.
• Calculate your absences carefully. For the long residence route, use the rules that apply to each part of your qualifying period: the pre-April 2024 rules for earlier time and the rolling 180-day rule for later time.
• Disclose everything relevant. Convictions, cautions, previous refusals, past identity issues, and overstays must all be declared. Non-disclosure causes more damage than the underlying issue in the vast majority of cases.
• If you have a criminal record, take legal advice before applying. The framework has tightened since March 2026, and the consequences of applying when the suitability criteria are not met include refusal and the loss of application fees.
• If your relationship has broken down and your leave is based on that relationship, notify the Home Office promptly and take advice on alternative routes before your status is curtailed.
• If a previous application involved inaccurate identity information, take specialist advice on how to address that history before making a new application. The approach taken to disclosure can significantly affect the outcome.

Frequently Asked Questions

Do absences abroad automatically disqualify me from long residence ILR?

No, absences do not automatically disqualify you, but they must fall within the permitted limits. For time before 11 April 2024, total absences across the qualifying decade must not exceed 548 days, with no single absence over 184 days. For time from that date onwards, no more than 180 days in any rolling 12-month period is allowed. Absences beyond those limits may break continuous residence, but the Home Office can exercise discretion in genuine exceptional circumstances if supported by strong evidence.

Can I get ILR or citizenship if I have a criminal conviction?

Yes, in some circumstances, though it depends on the sentence and the nature of the offence. Any custodial sentence of 12 months or more leads to mandatory refusal for both ILR and citizenship applications. For lesser offences, the Home Office considers the type of offence, how long ago it happened, and the overall pattern of behaviour. Full disclosure is essential; concealing a conviction is likely to cause more harm than the conviction itself.

Will a previous ILR refusal prevent me from applying again?

No, a previous refusal does not permanently prevent a further application. The new application will be examined more closely, and the Home Office will look to see whether the reason for the earlier refusal has been addressed. Where the refusal involved deception, a 10-year ban may apply, but for refusals on other grounds, a well-prepared fresh application addressing the earlier issues can succeed.

I used a different name or nationality in a past application. Can I still get ILR?

Yes, it may still be possible, but this is one of the most serious categories of issue under the Part Suitability rules, and it requires careful handling. Deception in an immigration application normally triggers a 10-year re-entry ban. However, the Home Office has discretion in some cases, and where the position has since been corrected, the circumstances are fully explained, and the overall history demonstrates lawful compliance, a path forward may exist. Specialist legal advice is essential before making any application.

My divorce is pending. Can I still apply for ILR?

Yes, if you are applying under the long residence route, a pending divorce has no effect on your eligibility. Long residence ILR depends on continuous lawful residence, not on your marital status. If you are applying on the spouse route, the position is more complicated, as your leave depends on the relationship. In that case, taking immediate legal advice before notifying the Home Office will help you understand which alternative routes may be open to you.
