Home Office Immigration Letters Decoded (UK 2026)

Changing fast: Physical BRP cards stopped being valid at the end of 2024 and the eVisa system is now the default, with the last window to use an expired BRP to set up a UKVI account closing on 31 December 2026. Separate changes to administrative review rules take effect on 8 October 2026.At a glance

• Home Office letters fall into four broad families: grants, refusals, requests for more information, and curtailment or revocation warnings.
• Only some letters carry a legal deadline. A refusal notice usually does — typically 14 days if you are in the UK, 28 days if you applied from abroad.
• Your rights are written into the letter itself. The paragraph headed something like "What you can do next" tells you whether you have an appeal, an administrative review, or neither.
• Administrative review costs £80 and only fixes caseworking errors — it is not a second bite at the application.
• A letter that only asks you to verify your identity or set up an account is not a decision and does not affect your status.
• Not legal advice: This article explains the rules in plain English. For your specific situation, speak to an OISC-regulated immigration adviser, an immigration solicitor, or Citizens Advice.

Very few pieces of post carry the weight of a Home Office envelope. It is often thin, the formatting is plain, and the first line rarely tells you whether the news is good. People open them on the doormat and read the same paragraph four times.

Part of the problem is that Home Office correspondence is written for two audiences at once. It has to be legally precise enough to stand up if a decision is challenged, and it has to be understandable to someone who may be reading English as a second, third or fourth language. Precision usually wins.

This guide walks through the letters people actually receive, what each one is doing, and — crucially — which ones start a clock running.

The four families of Home Office letter

Almost everything that lands from UK Visas and Immigration (UKVI) or the Home Office falls into one of four groups. Working out which group you are holding is the first and most useful thing you can do.

1. Grant letters and decision notices in your favour

A grant letter confirms that permission has been given. It will state the immigration route, the start and end date of your permission, and any conditions attached — the right to work, the right to study, and whether you can access public funds.

Since the move to digital status, a grant letter is usually not proof of status on its own. Your actual proof lives in your UKVI account as an eVisa, linked to your passport number. The letter is the explanation; the eVisa is the evidence.

What to check: the dates, the spelling of your name against your passport, and the conditions. If the conditions say "no recourse to public funds" and you believed otherwise, that is worth raising promptly.

2. Refusal letters and decision notices against you

These are the letters that carry deadlines. A refusal will typically set out the rule or paragraph relied on, a summary of the evidence considered, and the reasons the caseworker was not satisfied.

Near the end there will be a section — often titled "What you can do next" or similar — explaining your options. Read that section before anything else. It is the part with legal effect.

3. Requests for further information

These go by various names: a request for further evidence, a request for documents, an invitation to interview, or a biometric enrolment letter. They are not decisions. Your application is still live.

They usually do carry a response deadline, though, and missing it can lead to the application being decided on what is already on file — which rarely helps.

4. Curtailment, revocation and enforcement letters

These are letters about permission you already have. Curtailment means the Home Office intends to cut your existing permission short. Revocation means withdrawing it. Both usually follow a change in circumstances — a sponsor losing their licence, a course ending early, or a job finishing.

These letters often come in two stages: first a letter saying the Home Office is considering action and inviting representations, then a decision. The first stage is an opportunity, not a formality.

The words that actually mean something

A few phrases recur constantly and are worth learning.

• Leave to remain / leave to enter — "leave" simply means permission. Leave to remain is permission granted while you are in the UK; leave to enter is granted before you arrive.
• Conditions of leave — the rules attached to your permission. Work, study, public funds, and sometimes police registration.
• Curtailment — shortening permission you already hold.
• Administrative review — an internal Home Office reconsideration looking for caseworking errors.
• Right of appeal — a challenge heard by an independent tribunal, not by the Home Office. Much stronger, but available in far fewer cases.
• Section 3C leave — automatic extension of your existing permission while an in-time application is pending. This is why applying before your current permission expires matters so much.
• Genuineness — where a letter says a caseworker was not satisfied an application was "genuine", it means the evidence did not persuade them, not necessarily that they believe you lied.

Deadlines: the part people miss

If your letter is a refusal, the single most important thing is the date it was served and how long you have to respond.

Broadly, and subject to your specific route:

• Applied from inside the UK: usually 14 calendar days from receiving the decision to apply for administrative review.
• Applied from outside the UK (entry clearance): usually 28 calendar days from receiving the decision notice.
• Appeal rights, where they exist: commonly 14 days in-country and 28 days out-of-country, but the letter will state the figure that applies to you.

These are calendar days, not working days, and they run from service of the decision — which for an emailed decision is usually the day it is sent, not the day you opened it.

Administrative review versus appeal

People use these interchangeably. They are very different things.

Administrative review is the Home Office checking its own homework. It costs £80 and looks only for caseworking errors: evidence that was submitted but overlooked, a rule applied incorrectly, a calculation error. You generally cannot submit new evidence. If the decision was defensible on what you originally sent, administrative review will not help you.

An appeal goes to the First-tier Tribunal, which is independent of the Home Office. Appeals are available in far fewer categories — principally human rights and protection claims — but they allow a judge to look at the case afresh.

Not every refusal gets either. Visitor visa refusals and some short-term routes have no review or appeal right at all, and the practical option is usually a fresh application addressing the reasons given.

eVisas: what the account letters actually are

Because the transition to digital status is still bedding in, a lot of Home Office post right now is administrative rather than decisional — letters and emails asking you to create a UKVI account, verify identity, or update a passport number.

These are worth acting on, but they are not threats. Creating a UKVI account is free, involves no application and no decision, and does not change your immigration rights. The status you hold exists in the Home Office database regardless of whether you have set the account up.

One point that causes real anxiety: BRP cards that expired on 31 December 2024 did not take anyone's status with them. The card expired; the underlying permission continued. The expired card can be used to establish the account until the end of 2026.

What to do when a letter arrives

1. Photograph or scan it immediately, including the envelope if it shows a postmark. Date of service matters.
2. Find the "what you can do next" section and note the deadline in your calendar with a reminder several days early.
3. Identify which family it belongs to — grant, refusal, request, or curtailment. That determines urgency.
4. Read the reasons carefully if it is a refusal. Vague dissatisfaction with evidence is a very different problem from an allegation of deception.
5. Get advice before the deadline, not after. A regulated adviser or immigration solicitor can tell you in one conversation whether review, appeal or reapplication is the right route.
6. Do not stop engaging. Ignoring curtailment correspondence rarely improves the outcome and can limit the options later.

Where to get help

Immigration advice in the UK is regulated. Anyone giving it for a fee must be a solicitor, a barrister, or regulated by the Immigration Advice Authority (formerly OISC). You can check an adviser's registration before paying anything.

Free and low-cost help exists too: Citizens Advice for general signposting, law centres in many cities, and several charities specialising in particular routes. Waiting lists can be long, which is another reason to start the moment a letter arrives rather than the week the deadline falls.

Before you pay for advice, understand what you're holding. Clarify turns a dense refusal notice into plain English in under a minute — the reasons given, the deadline, and which challenge route the letter says is open to you. Walk into your adviser appointment already knowing the right questions.

Frequently asked questions

Is a Home Office letter still valid if it arrives by email?

Yes. Decisions are routinely served by email and the deadline usually runs from the date the email was sent, not the date you read it. Check your spam folder regularly while an application is pending.

My BRP expired at the end of 2024 — have I lost my status?

No. The card expired, not the permission behind it. Your status continues and is now held digitally. You can use the expired card to create a UKVI account until 31 December 2026.

What is the difference between a refusal and a rejection?

A refusal is a decision on the merits of your application. A rejection usually means the application was invalid — a fee unpaid, biometrics not provided, or a mandatory section left blank. Rejections are often fixable by reapplying correctly.

Does applying for administrative review extend my permission?

In some in-country cases it can, through section 3C leave, but this is route-specific and not automatic in every circumstance. Because the consequences of getting this wrong are serious, check with a regulated adviser rather than assuming.

How much does administrative review cost?

£80. The fee is refunded if the review succeeds. It is not refunded if the decision is maintained.

Can I send new documents with an administrative review?

Generally no. Administrative review examines whether the original decision contained a caseworking error based on what was already before the caseworker. If your case needs new evidence, a fresh application is usually the better route.

What does "no recourse to public funds" mean on my letter?

It is a condition preventing you from claiming most benefits, including Universal Credit and housing assistance. It can sometimes be lifted if you are destitute or there are welfare concerns involving a child, but that requires a separate application.

The letter mentions curtailment but no decision has been made — what should I do?

Treat it as urgent. A letter inviting representations is your chance to explain your circumstances before a decision is taken, and that window is usually short. Get advice within days, not weeks.
