Effective today, January 26, 2021, all air travelers 2 years of age and older (including US citizens and LPRs) entering the United States are required to present to the airline a negative covid test taken within 72 hours of departure (or proof of recovery within the last 90 days). Additional information may be found at https://www.cdc.gov/coronavirus/2019-ncov/travelers/testing-international-air-travelers.html
Pursuant to Pres. Biden Presidential Proclamation of January 25, 2021, entry of foreign nationals who were physically present in the Schengen Area within 14 days prior to arrival at the port of entry in the United States continues to be suspended even with a negative covid test, subject to certain exceptions.
Certain travelers may continue to be eligible to apply for a National Interest Exception ("NIE") for travel to the United States; however, please note that NIE's consular processing is backlogged and increased wait times should be expected (currently, up to 60 days at the Embassy and Consulates in Italy). Both visa holders and ESTA travelers may apply for a NIE.
