Letters of invitation

Please submit your request online for letters of invitation.


Tips for a successful letter request:

  • You can only submit your request once for the system to operate smoothly. Multiple submissions are not accepted by the system. 
  • All starred* information is required.
  • Respect the format of the request form. For example, the date must be DD/MM/YYYY and the punctuation is required in order for the submission to be accepted.
  • Information should be entered as it is shown on your passport.
  • Capital letters should only be used for initial characters. Please do not use all capital letters when filling in the form.
  • The maximum number of characters allowed is 55 (including spaces) for the organisation, job title and address fields.
  • Double check all the information you enter carefully. It will appear as entered, including obvious errors.

Further notes of importance:

  • To enter the UK, your passport must be valid for a minimum of six months from your date of entry.
  • Your letter of invitation can only cover the official dates of the conference. Any travel requirements outside of the conference dates must be explained to the embassy in your visa application.


Conference delegates: The conference is open to all delegates directly or indirectly involved in activities related to TB, HIV, lung health (asthma, paediatric pneumonia, COPD, etc) tobacco control and public health, in general.

The Union reserves the right to reject requests for letters of invitation that are not related to the conference.

Contributors to the scientific programme: If you will be contributing to the conference programme as a chair, speaker, coordinator or abstract author, you may request that the session you are involved with be mentioned in your letter of invitation. Please enter the session's full reference (the session name and number specified in the information provided to you) in the comments section of your submission form.

Accompanying persons: All accompanying persons must submit separate requests for letters of invitation through our system following the instructions above.

Applying for another person: You may apply for a letter of invitation on behalf of another person. However, you will need to ensure that you have all the applicant’s details (name, address, DOB, passport details, etc) in order to submit the online request.

Languages: Letters are only available in English.


Once the online letter of invitation has been requested, an automatic email acknowledgement will be sent immediately to the submitter.

Although requests may be submitted beginning 30 March, the processing will not begin until early May when the scientific programme has been confirmed.

Online: Requests will be processed beginning in early May.

Post: On request, original letters of invitation can be sent to you by postal mail, and the date of receipt will depend on your local postal service.

Express mail: The original letter may also be sent by courier or express mail, if required. You will be responsible for organising the courier service and pay all costs incurred.

In person: Letters of invitation may also be collected in person, Monday through Friday, 09:00–18:00 at the following address:

International Union Against Tuberculosis and Lung Disease (The Union)
68 boulevard Saint-Michel

  • The deadline for submitting a request for a letter of invitation is 10 October 2016.
  • No letter will be processed after this date.

Applying for your visa

Once you have your letter of invitation, you need to apply for your visa. Delegates are responsible for making their own arrangements for getting a visa and are urged to contact their nearest UK embassy or consulate as early as possible to determine where they should apply and to enquire on the length of time expected to complete the visa process.
