To be considered fully vaccinated, it must be at least two weeks after receiving a second dose in a two-dose series or at least two weeks after receiving a dose of a single-dose vaccine.
USCIS has eased other requirements for fully vaccinated individuals who do not have COVID-19 symptoms. Those who have returned from domestic air, international air or cruise ship travel in the past 10 days may enter USCIS facilities if they are fully vaccinated. Individuals who have been in close contact (within six feet for a total of 15 minutes or more) with anyone known to have COVID-19 in the previous 14 days may also enter USCIS facilities if they are fully vaccinated. Healthcare workers who consistently wear an N95 respirator and proper personal protective equipment or equivalent when in contact with COVID-19 positive individuals continue to be exempt from reporting close contact.
In DHS-controlled spaces, this guidance supersedes state, local, tribal, or territorial rules and regulations regarding face coverings.
