Effective October 1, 2021, by order of the Center for Disease Control and Prevention, the USCIS and the U.S. Department of State will require permanent residency visa applicants to be vaccinated against Covid-19. Proof of full vaccination will be required along with other vaccination requirements already in place. Must present proof of covid-19 vaccine: those who file an adjustment of status request (I-485) and who are filling out the I-693 medical exam form after the 1st. October 2021. Remembering that the exam must be done by a doctor authorized by the USCIS. Those who file an immigration visa at a US consulate abroad must also take the exam with USCIS-authorized physicians.
If the medical exam (I-693) is completed before October 1, 2021 and the exam results are within the validity period (typically 2 years from completion, with some exceptions), vaccination is not required. Those with an inappropriate age for vaccination, or those whose vaccination is contraindicated, are exempt from the decision.
