The K-3 visa process involves, among other requirements, undergoing a medical examination, which includes verification of the vaccination history. This step is crucial to ensure that the applicant does not pose health risks to the American population, following guidelines established by the Centers for Disease Control and Prevention (CDC) and United States immigration laws.

Generally, the required vaccines include immunizations against measles, mumps, and rubella (MMR), chickenpox, poliomyelitis, diphtheria, tetanus, and pertussis (Tdap or DTaP), and hepatitis B. Depending on the time of year, age, and other factors, vaccination against influenza and other supplementary vaccines may be recommended.

The list can be updated according to new recommendations or public health emergencies. It is essential that applicants consult the most recent CDC guidelines and complete the medical examination with an authorized professional to ensure compliance. Avoid information from unofficial sources, always seeking guidance from government websites and qualified professionals to prevent jeopardizing the process.
