I am a new student applying from a NIE country (can I enter the USA)? I have my F-1 visa.

Yes, on June 29, 2021, the Department of State extended the validity of National Interest Exceptions (NIE) for travelers subject to restrictions. Unless otherwise indicated, existing NIEs will be valid for 12 months from the date of approval and for multiple entries, as long as they are used for the purpose under which they were granted. This extension applies to travelers from China, Iran, Brazil, South Africa, the Schengen Area, the United Kingdom, Ireland and India.
