IOM Colombo TB Test for a UK Student Visa: What Sri Lankan Applicants Need to Know

TL;DR: If you are a Sri Lankan applying for a UK Student visa for a course of six months or more, you need a tuberculosis (TB) test certificate from the IOM clinic in Colombo 08, the only Home Office approved TB clinic in Sri Lanka. The test is a chest X-ray. The certificate lasts six months from the X-ray date, so book it close to your visa application, not months ahead.

The IOM Colombo TB test is one of the smallest steps in a UK Student visa application, and one of the easiest to get wrong on timing. Book too early and the certificate can expire before you apply. Book too late, in the June to September peak, and a wait of up to 10 days can push back your visa.

Who needs the TB test

The Home Office guidance on TB tests for visa applicants says you must have a test if all three of these apply:

• You are coming to the UK for six months or more.
• You have lived in a listed country for six months or more.
• You were living there, or in another listed country, within the last six months.

Sri Lanka is on the list. So if you live in Sri Lanka and your course runs for six months or longer, you need the test. Students are not among the exempt groups.

The IOM Colombo clinic in brief

The Home Office page on TB testing in Sri Lanka names one approved clinic, run by the International Organization for Migration (IOM).

Book by phone or email; the contact details are on the Home Office page listed in our references. A test from any other hospital or private X-ray centre in Sri Lanka will not be accepted for your visa.

What to bring on the day

The Home Office page asks you to bring:

1. Your passport and a valid photo ID.
2. The test fee in Sri Lankan rupees.
3. Your address in Sri Lanka and your intended address in the UK.
4. Two recent passport-sized colour photographs.
5. Medical records of any past TB or lung disease, if you have them.

IOM's own health assessment guidance adds a few practical points: arrive about 15 minutes early, wear clothes that are easy to remove for the X-ray, and bring any previous chest X-ray you have. Your UK address can be your university accommodation or a provisional address. Check with the clinic when you book if you are unsure what to write.

What happens at the test

The test is a chest X-ray. If the X-ray is clear, the clinic issues a certificate. The Home Office guidance says to include this certificate with your UK visa application.

If the X-ray result is not clear, you may be asked for a sputum sample, which is phlegm coughed up from your lungs. The Home Office warns that sputum testing can mean an extra fee and a wait of up to eight weeks for results. This is uncommon, but it is the main reason not to leave the test to the final week before your visa appointment.

Children under 11 are usually seen by a clinician who completes a health questionnaire rather than an X-ray. Pregnant applicants have separate options, set out in the Home Office guidance.

When to take the test in your visa timeline

This is where most avoidable problems start. Two six-month rules sit side by side:

• The certificate is valid for six months from the date of your X-ray.
• The earliest you can apply for a Student visa from outside the UK is six months before your course starts.

In practice, take the test after your offer is firm and your CAS is close, then apply for the visa soon after. That keeps the certificate well inside its six months when a caseworker reads it. A test taken in February for a January start expires in August, before most students even have a CAS. If your intake is in September, the clinic's June to September peak lands right on top of your visa window, so book as soon as your dates are clear.

Our UK January intake timeline for Sri Lankan students shows where each step falls. If your university runs a pre-CAS check first, our guide to pre-CAS interview questions will help you prepare.

Frequently asked questions

Where can I get a TB test for a UK visa in Sri Lanka? Only at the IOM Migration Health Assessment Center on Elvitigala Mawatha, Colombo 08. It is the one Home Office approved clinic in Sri Lanka.

How much is the IOM Colombo TB test? The Home Office page lists USD 60 for applicants aged 11 and over and USD 30 for under 11, charged in rupees at the UN monthly exchange rate.

How long is the UK TB certificate valid? Six months from the date of your chest X-ray.

Do I need a TB test for a one-year master's in the UK? Yes, if you have been living in Sri Lanka. A one-year course means staying in the UK for six months or more.

What if my X-ray is not clear? You may be asked for a sputum sample. Results can take up to eight weeks, which is why booking early in your visa window matters.

PS: The TB test is quick, but its six-month life means it has to be timed against your CAS and course start date. If you want help mapping your UK course, offer and visa steps in the right order, check your eligibility with Prosper and we will plan it with you.
