Your approved waiver will stay valid until either its expiration date or until it is revoked by CBP. If you have been granted a waiver by the U.S. Customs and Border Protection (CBP), it means that you have been exempted from certain requirements that are normally imposed on travelers entering or leaving the United States. The statement “Your approved waiver will stay valid until either its expiration date or until it is revoked by CBP” means that once CBP has approved your waiver application, it will remain in effect until either the expiration date specified in the waiver or until CBP decides to revoke it.
In other words, you can use your waiver to travel in and out of the United States during the validity period specified in the waiver without having to fulfill certain requirements that would normally be required of travelers. However, it’s important to note that CBP retains the right to revoke your waiver at any time, so you should always ensure that you are in compliance with any conditions or restrictions specified in your waiver, as well as with any applicable U.S. laws and regulations governing travel and immigration.
