Due to the updated CDC guidelines, USCIS has updated its visitor policy. Fully vaccinated people should no longer wear protective masks. However, persons aged two years or older who have not received a full vaccination must still wear a mask.
To be considered fully vaccinated, it must be at least two weeks after receiving the second dose in a two-dose series, or at least two weeks after receiving a single dose of vaccine.
USCIS has simplified other requirements for fully vaccinated individuals who are asymptomatic of COVID-19. Those returning from domestic, international, or cruise flights within the past 10 days may enter USCIS facilities as long as they are fully vaccinated. Individuals who have been in close contact (within six feet for a total of 15 minutes or more) with someone with knowledge of COVID-19 in the previous 14 days can also enter USCIS facilities if fully vaccinated. … Healthcare professionals who wear an N95 respirator and appropriate personal protective equipment at all times when coming into contact with people infected with COVID-19 are still exempt from reporting close contact.
