Who normally needs a TB test for a UK visa application?
A test is normally required where the applicant is coming to the UK for six months or more, has lived in a listed country for six months or more, and lived there or in another listed country within the six months before the application. All parts of the test must be considered.
Can a TB test be required for a stay of less than six months?
Yes. Applicants coming as a fiancé, fiancée or proposed civil partner, and certain returning residents, may need a test even where the intended permission is for less than six months.
Where must the test be completed?
The test must be completed at a clinic approved by the Home Office. A certificate from a non-approved clinic will not normally meet the immigration requirement. Applicants should use the current GOV.UK country and clinic list.
What happens during the test?
The clinic will assess the applicant for pulmonary tuberculosis. Adults will normally have a chest X-ray and may need further testing if the result is unclear. The clinic decides what examinations are medically appropriate.
Do children need to attend a clinic?
Yes. Children must attend an approved clinic for assessment. Children under 11 will not normally have a chest X-ray, but the clinician will decide whether testing is required and issue a certificate where the child is assessed as free from pulmonary tuberculosis.
What happens if the result is positive?
The clinic will not issue a TB clearance certificate and will refer the applicant for treatment. The applicant will not be able to satisfy the TB certificate requirement until medically cleared and issued the required certificate.
How long is a TB certificate valid?
A TB certificate is normally valid for six months from the date of the chest X-ray. The certificate must still be valid when the immigration application is made, and timing should be considered if the application is delayed.
Should the website list every country that requires testing?
No. The list can change and different circumstances affect whether a test is required. UKU should link to the current GOV.UK country and clinic pages rather than reproduce a static list.
