Residents of Bolivia who wish to come to the UK for more than 6 months must be tested for tuberculosis (TB) before applying for a visa.
If you submit an application at the British Embassy in La Paz on or after 31 October 2013, you will need to take a TB test if you are applying to come to the UK for 6 months or longer. If you apply for a visa before this date you will not need to take a TB test.
If you plan to come to the UK for less than 6 months you do not need a TB test, unless you are applying for a 6 month fiancé (e) visa.
For detailed information about the testing process and requirements, see the TB testing information on the Home Office’s UK visa website for Bolivia
