UK Migration Health Assessment guide cover — IOM Colombo TB screening for UK visa applicants from Sri Lanka.

UK Migration Health Assessment in Sri Lanka: IOM Colombo Guide

April 27, 20266 min read

If you’re applying for a UK visa of six months or longer from Sri Lanka, you’ll need a tuberculosis (TB) screening certificate. Here’s exactly what to expect at the IOM Migration Health Assessment Centre in Colombo — and the small details that catch most applicants off guard.

The UK requires TB screening for visa applicants from countries with a high TB burden, including Sri Lanka. The screening must be done at an approved International Organization for Migration (IOM) clinic — for Sri Lanka, that means the IOM Migration Health Assessment Centre (MHAC) in Colombo. No other clinic’s certificate will be accepted.

Most applicants find the process straightforward once they know what to expect. The full appointment usually takes 1–2 hours, and your TB certificate is typically issued the same day if your chest X-ray is clear.

Who needs a UK migration health assessment?

You need TB screening at IOM Colombo if you meet both of these conditions:

  • You’re applying for a UK visa of six months or longer (student, work, family, dependant, or settlement)

  • You’ve been living in or have travelled to a country on the UK’s TB-screening list within the last six months — Sri Lanka is on this list

Visitor visas under six months don’t usually require TB screening. If you’re unsure whether your visa category needs it, the UK government’s official TB screening guidance lists the requirements by visa type.

When to book your appointment

This is the single most important detail most applicants miss: your IOM TB certificate is valid for only six months from the date of issue. If your visa is refused or delayed past that window, you’ll have to redo the screening and pay again.

Recommended timing: book your IOM appointment within 4–6 weeks of your planned UK visa application date. Early enough to have the certificate in hand when you submit, late enough that the certificate won’t expire before your visa is issued.

IOM Migration Health Assessment Centre — Colombo

What to expect on the day

The standard process at IOM has four stages:

  • Registration — present your documents at reception.

  • Counselling — a short briefing on the assessment process; you’ll sign an informed consent form.

  • Medical examination — review of medical history, physical examination if clinically indicated, and a chest X-ray (for applicants 11 and older).

  • Clearance certificate — issued the same day if all tests are normal.

What’s tested by age group

Children under 11 years:

  • Medical history and symptoms review

  • Physical examination if clinically indicated

  • No chest X-ray required

Applicants 11 and older:

  • Medical history and symptoms review

  • Physical examination if clinically indicated

  • Chest X-ray

Special considerations

Children and minors

Applicants under 18 must be accompanied by a parent or legal guardian who can provide consent. If the parent can’t attend, the accompanying guardian must bring a legal authorisation letter.

Pregnancy

If you’re a woman of childbearing age, you may be asked to provide a urine sample for a pregnancy test before the chest X-ray. If you’re pregnant, you have three options:

•Proceed with the chest X-ray using double lead shielding

•Opt for sputum testing instead — three samples over three consecutive days

•Postpone the assessment until after delivery

None of these options affect your visa decision. Don’t conceal pregnancy — disclose it at registration.

If TB is suspected

If your chest X-ray or symptoms raise concerns, the doctor will request sputum samples taken over three consecutive days. Lab results take 8–10 weeks. If active TB is confirmed, you’ll need to complete treatment before your immigration process can continue. Latent TB (no active symptoms) doesn’t usually disqualify you, but it must be documented.

What to bring

Identification:

  • Original passport

  • National ID card or driving licence

  • For minors: photo ID of the accompanying parent or guardian, plus original birth certificate and a photocopy

Medical records:

  • Any previous chest X-rays — particularly if you’ve been diagnosed with or treated for TB before

Other documents:

  • Two recent passport-size colour photographs with a white background

  • Your full Sri Lankan address (with phone and email) and your full UK address (with postcode and phone)

  • Your UK sponsor’s full name, if you’re a dependant

Fees and payment

IOM Colombo charges in US dollars but accepts payment in Sri Lankan rupees on the day:

  • Children under 11: USD 30 (LKR equivalent at the day’s rate)

  • 11 and older: USD 60 (LKR equivalent at the day’s rate)

Cash only. No card or bank transfer payments are accepted at the centre. Bring rupees, not dollars.

Practical advice for the day

  • Arrive 15 minutes before your scheduled appointment.

  • You don’t need to fast.

  • If a physical examination is needed, you’ll be asked to change into a medical gown (underwear stays on). You can request a chaperone.

  • Only the applicant is allowed inside the centre — companions and family wait outside. The exception: a parent or guardian for a minor.

  • If you or your child are unwell on the day, reschedule. Don’t attend with a fever or active illness.

Bring an umbrella — there’s no covered waiting area outside the building.

Frequently asked questions

How long is the IOM TB certificate valid?

Six months from the date of issue. Apply for your UK visa within this window or you’ll need to repeat the screening.

Can I do the TB screening at any clinic?

No. The UK Home Office only accepts certificates from IOM-approved clinics. In Sri Lanka, that’s the IOM Migration Health Assessment Centre in Colombo. Certificates from any other doctor or hospital will be rejected.

How long does the appointment take?

Allow 1.5 to 2 hours for the full process, including registration, counselling, examination, X-ray, and certificate issuance.

What if I have latent TB?

Latent TB (no active symptoms) doesn’t usually prevent visa approval, but the diagnosis must be documented in your medical records. Active TB requires complete treatment before your visa process can continue.

Do I need a referral from my doctor?

No. You book directly with IOM — no GP referral needed.

Can I reschedule if I’m sick on the day?

Yes, and you should. Contact IOM by phone or email as soon as possible to rebook.

Final checklist

Before you leave home for your IOM appointment, confirm you have:

  • Original passport

  • National ID or driving licence

  • Two passport-size photos (white background)

  • Sri Lankan and UK addresses with contact details

  • Sponsor’s name (if a dependant)

  • Sufficient cash in LKR (~LKR 18,000–20,000 for adults at current rates)

  • Previous medical records or chest X-rays (if applicable)

  • Birth certificate and parent/guardian ID (for minors)
