A visa applicant will need to include a Tuberculosis screening test results with their visa application if
Those who are resident in these countries must undergo screening of active pulmonary tuberculosis (TB) at a Home Office approved medical practitioner. Please refer to the Home Office TB overview page for the list of countries affected, country-specific guidance in relation to the process and testing for dependants (including children), and the lists of approved testing clinics in each country.
If the visa applicant is free from active pulmonary tuberculosis, the medical certificate should be included in their visa application. The Home Office recommends that the certificate is carried in their hand luggage when travelling to the UK so this can be presented to the immigration officer on arrival.
Where TB is detected a medical certificate will not be issued until after treatment has been received (which can take up to 6 months), the applicant can show that they have had treatment, and that they then are free from TB. It is important that applicants from countries where TB pre-screening is required are tested as soon as possible in advance of their application as additional tests and/or treatment will significantly delay their application to come to the UK.
