How long UKVI should take
UKVI publishes service standards for Student and Child Student applications. The usual guidance is that you should get a decision within three weeks if you applied from outside the UK, and within eight weeks if you applied from inside the UK, unless you paid for a priority or super priority service. These are targets rather than legally binding deadlines, and the published average processing times can change with demand.
Your application can legitimately take longer than the standard in a number of situations, for example where documents need to be verified, where you have been asked for further evidence such as proof of funds or a valid CAS, where an interview is required, where there are questions about your immigration history or a criminal record, or where UKVI is dealing with unusually high volumes. A delay on its own is not evidence of any error or unlawful conduct, so it is worth establishing the likely cause before treating it as a problem that needs escalating.
First step: check your status and the current standard
Before doing anything else, confirm exactly where your application stands.
1. Check the current published processing time for your specific route and whether you applied in or out of the UK, so you know whether you are genuinely outside the standard.
2. Check whether UKVI has contacted you, including your spam folder and any email address used on the application. UKVI often emails to request further evidence or to say a case is complex, and a missed request is a very common reason for apparent delay.
3. Check whether you paid for a standard, priority or super priority service, because your expectations and remedies differ depending on what you paid for.
Contacting UKVI for an update
If you are past the current standard and have not been contacted, GOV.UK expressly invites you to contact UKVI for an update. Use the appropriate contact route for where you applied.
For applications made inside the UK, contact UK Visas and Immigration through the online contact form or the UKVCAS enquiry channels. For applications made outside the UK, contact the international enquiry service (TLScontact or VFS Global, depending on your country) or the UKVI international contact centre.
Keep your application (GWF or UAN) reference to hand, and keep a dated record of every contact and response. A polite, factual chase asking for an update and an expected decision date is often enough to move a case that has simply been sitting in a queue.
Making a formal complaint about delay
If contacting UKVI does not produce a meaningful response, you can use the UKVI complaints procedure. A complaint about delay should set out your reference numbers, the date you applied, the relevant service standard, the fact that you are outside it, and the impact the delay is having, for example an approaching course start date or an expiring current visa. UKVI aims to respond to complaints within a set period, and a well-evidenced complaint referring to your course start date can prompt prioritisation.
If you are unhappy with how your complaint is handled, you can escalate to the Parliamentary and Health Service Ombudsman via your MP, although this is a slower route and is about complaint handling rather than forcing a decision.
Asking your MP to intervene
Contacting your constituency MP is a practical and often effective step where a delay is causing real harm, such as a missed enrolment date. MPs have a dedicated channel to UKVI for account enquiries and can ask UKVI to explain or expedite. This is low cost and low risk and is worth doing in parallel with a complaint.
Involving your sponsor
Your education provider is your visa sponsor and has an interest in you enrolling on time. Many universities and colleges have a compliance or international student advice team with contacts at UKVI and experience of chasing delayed decisions. Ask them to support you, and ask whether they can offer a late enrolment or deferral if the decision does not arrive before your course starts. This protects your position while the application is outstanding.
Legal remedy for unreasonable delay
If UKVI has failed to decide within a reasonable time and the informal routes have been exhausted, the legal remedy for an unlawfully delayed decision is judicial review in the Upper Tribunal (Immigration and Asylum Chamber) or the Administrative Court, seeking a mandatory order compelling UKVI to make a decision. The court does not decide the visa itself; it orders the Home Office to decide it.
What amounts to unreasonable delay is fact-sensitive. Being modestly over the published service standard is not usually enough on its own, especially where UKVI has a legitimate reason such as pending checks. A stronger case arises where the delay is substantial, unexplained, well beyond the standard, and is causing serious prejudice, and where you have already chased and complained without result.
The proper first step before any claim is a pre-action protocol letter (a letter before claim) to the Home Office, setting out the facts, the delay, why it is unlawful, and a deadline for a decision, warning that you will issue proceedings if none is made. In many cases this letter alone produces a decision, because the Home Office would rather decide the case than defend a claim.
Judicial review carries real cost, delay and litigation risk, and it should be treated as a last resort after the update request, complaint, MP contact and pre-action letter. Because time limits and procedure for judicial review are strict, if you are contemplating this route it is worth acting promptly rather than letting matters drift.
Protecting your immigration position while you wait
If you applied from inside the UK before your previous leave expired, your existing leave and its conditions are automatically extended under section 3C of the Immigration Act 1971 until your application is decided (and while any in-time appeal or administrative review is pending). This means you generally do not become an overstayer merely because the decision is delayed, and you can usually continue to live, and in many cases study or work within your existing conditions, while you wait. Do not travel outside the UK while an in-country application is pending, because leaving usually causes the application to be treated as withdrawn.
Practical points on timing and enrolment
Speak to your provider early about the latest date you can enrol and whether a short deferral is possible, so a delayed decision does not cost you your place. Keep evidence of the harm the delay is causing, including your CAS start date and any communications with your provider, because this evidence strengthens both a complaint and any later legal step.
Suggested order of action
1. Confirm you are genuinely outside the current published processing time and check for any missed UKVI request for evidence.
2. Contact UKVI for an update using the correct channel for where you applied, keeping a dated record.
3. Tell your sponsor and ask for support and, if needed, a late enrolment or deferral.
4. Make a formal complaint referring to the service standard and the impact on you.
5. Ask your MP to make an account enquiry to UKVI.
6. If the delay remains unreasonable and unexplained, send a pre-action protocol letter, and only then consider judicial review for a mandatory order.
Useful information I would need to be more specific
The best next step depends on details you have not given, in particular whether you applied from inside or outside the UK, the date you applied, how far past the service standard you are, whether you paid for priority or super priority, whether UKVI has asked you for anything, and when your course starts. If you tell me these, I can tailor the sequence and indicate whether your delay is at the point where a formal complaint or a pre-action letter is realistically justified.
