Immigrant visas are limited to the validity of the medical examination for a maximum of six months. Centers for Disease Control and Prevention approved a one-month extension for medical examinations conducted between January 1, 2020, and June 30, 2020. If you were unable to travel on your issued visa or obtained your medical examination but did not receive your visa, contact the Immigrant Visa Unit of the U.S. Embassy or Consulate that issued or is adjudicating your visa application to determine whether you may be issued or reissued a visa for one additional month. If you are not able to travel within the one additional month, consider waiting until you are able to travel and obtain a new, full validity medical examination and visa.
