TB Test for UK Visa: Who Needs It, How to Get It, and What Happens If You Skip It

A tuberculosis test certificate is not required for every UK Skilled Worker visa applicant — but if you are from one of the listed countries and you omit it, your application is refused immediately. There is no grace period and no opportunity to supply the document after submission. Here is exactly who needs it, how to obtain a valid certificate, and how the police clearance requirement works in parallel.

Who Needs a TB Test

The Home Office requires a TB test from applicants who:

1. Are applying from outside the UK (entry clearance)
2. Have lived for 6 months or more in the preceding 12 months in a country on the mandatory TB test list

The list covers most of South Asia (India, Pakistan, Bangladesh, Sri Lanka, Nepal), much of sub-Saharan Africa, parts of Southeast Asia (Philippines, Indonesia, Vietnam, Myanmar, Thailand), and a number of other countries. The full list is published on GOV.UK and is updated periodically.

If you are currently in the UK on a Student or Graduate visa and applying for an in-country switch to the Skilled Worker route, you generally do not need a new TB test — you provided one when you first entered the UK. The exception is if your original visa was granted more than 12 months ago without a TB certificate (which would only apply to nationalities that were not on the list at that time).

If you are outside the UK but have been living in a non-listed country for more than 6 months (for example, a Nigerian national who has been living in Canada for a year), the TB test requirement may not apply. The rule is about where you have been living, not your nationality.

The Test Must Come From an Approved Clinic

This is where applicants go wrong. You cannot get a chest X-ray from any hospital or private clinic and submit it. The test must be conducted at a clinic that is specifically approved and listed on the Home Office's official panel.

Approved clinics exist in all countries where the test is required. In India, there are approved IOM and private clinics in major cities including Delhi, Mumbai, Chennai, Kolkata, and others. In Nigeria, approved clinics operate in Lagos, Abuja, and Kano. In the Philippines, IOM Manila handles a large share of applicants.

The test process:

1. Book an appointment at an approved clinic
2. Attend in person — the test cannot be done remotely or by proxy
3. Undergo a chest X-ray (and a sputum test if there is any indication of active disease)
4. Receive the certificate from the clinic

Results are typically available within a few days. The certificate confirms you are clear of active pulmonary tuberculosis.

The certificate must be dated within 6 months of your visa application date. If you book the test too early and your visa application takes longer than expected, the certificate can expire. Many applicants apply for the TB test shortly after receiving their Certificate of Sponsorship and submit the visa application promptly to avoid this timing issue.

What the Certificate Contains

The approved clinic issues a standardised certificate in a format the Home Office recognises. It includes:

• Your name and date of birth
• Your passport number
• The date of the X-ray
• The name and address of the approved clinic
• A statement confirming the result (clear of active pulmonary TB)
• The clinic doctor's stamp or signature

You upload this document during the visa application process through the commercial partner portal. It is not sent separately.

Police Clearance: Who Needs It and How Authentication Works

Police clearance certificates are a separate requirement from the TB test and are not required from all Skilled Worker applicants. They are only mandatory if you will be working in certain regulated sectors — primarily healthcare, education, and social care.

The police clearance must cover every country where you have lived for 12 months or more in the past 10 years.

The reason many applications in these sectors fail is not the document itself but the authentication step that follows obtaining it. Most countries issue police clearance certificates as digital documents or PDFs. UK immigration officers typically cannot access foreign police databases to verify the authenticity of digital certificates, so a physical authentication stamp from the relevant foreign ministry is usually required.

India: The police clearance is obtained through the Passport Seva Portal or the local police station. India does not require a separate Ministry of Foreign Affairs authentication step. The police-issued document is sufficient.

Nigeria: The POSSAP online portal generates a PDF with a QR code. However, UK immigration officers cannot reliably verify Nigerian Police Force QR codes. The certificate must be physically authenticated with a stamp from the Ministry of Foreign Affairs in Abuja. Without this stamp, the POSSAP PDF is rejected. Standard MFA authentication takes 5 to 7 working days; it can take longer during peak periods.

Pakistan: Applicants from Punjab, Islamabad, and Azad Jammu and Kashmir can use the Police Khidmat Markaz (PKM) digital portal. Applicants from Sindh and Khyber Pakhtunkhwa must use a manual authority letter process, have it attested by the High Commission, and coordinate with a contact in Pakistan. The final certificate requires Ministry of Foreign Affairs (MOFA) attestation followed by UK High Commission attestation before it is acceptable for submission.

Philippines: The National Bureau of Investigation (NBI) Clearance is the required document. After in-person biometric capture at an NBI branch (note: a "Hit" result delays the process by 10 days for manual verification), the final clearance must be Apostilled by the Department of Foreign Affairs. An unapostilled NBI clearance is not sufficient.

Timing Both Documents in a Single Application

For applicants who need both a TB test and a police clearance certificate, the sequencing matters:

Start the police clearance process first if you are in a country with multi-step authentication (Nigeria, Pakistan, Philippines). MFA and High Commission attestation add weeks to the process.

Start the TB test approximately 4 to 8 weeks before you plan to submit the visa application. Earlier than that and you risk the 6-month validity window expiring.

Both documents should be ready and uploaded together with your main application pack. Uploading documents piecemeal after submission is not possible through the standard portal — what you upload is what UKVI reviews.

The UK Skilled Worker Visa Guide includes a country-by-country authentication guide for police clearances and a document timeline that sequences TB tests, Ecctis assessments, English tests, and bank statement windows so nothing expires before you submit.
