Important information concerning the medical examination for immigrant and K visa applicants at the U.S. Embassy in London
If you are applying for an immigrant, fiancee or K-3 or 4 visa at the Embassy, the medical examination must take place before the visa interview. If you arrive at the Embassy without having attended a medical examination, your interview will be cancelled and you will be required to schedule for a later date.
You should allow approximately 5 workdays between the medical examination and visa interview. Provided you have attended the examination, we will conduct the visa interview, even if we have not received the results of the medical examination. In such cases, action your application will be suspended until the results are received.
