The State Department has modified the validity of its national interest exceptions (NIEs) to a 12-month, multiple-entry validity, effective immediately.
Before, these NIEs were valid for 30 days and a single entry only. This change affects NIEs issued under all of the existing travel bans – for those present in the following countries within 14 days of trying to enter the United States: Brazil, China, India, Iran, South Africa, the Schengen Area, the United Kingdom, and Ireland.
This is effective immediately and also applies to NIEs issued in the last 12 months which can be used for 12 months after their initial approval (the purpose of travel must be the same)
At this time, however, U.S. Customs and Border Protection (CBP) has not changed the validity of NIEs issued at CBP ports of entry and pre-flight inspection sites. These will still be valid for 30 days.
We expect to get more clarity on these type of NIEs in the upcoming days.
