Applicants who live permanently in certain countries/regions who come to the UK for more than six months require a certificate to show that they are free from infectious pulmonary tuberculosis (TB).
The list of countries/regions is subject to change depending upon local conditions.
You do not need to apply for a TB certificate if you have lived for at least six months in a country that does not require TB screening, and you have been away from that country for no more than six months.
What is the TB test?
The TB test is a chest x-ray. You must get the test at a UKVI approved clinic. You will get a certificate which is valid for six months. You must include this with your visa application.
Carry your certificate
If you need a TB screening certificate, you should carry it in your hand luggage in case you need to present it to an immigration officer on arrival in the UK.
