When do I need to apply for a travel authorization?
Applications may be submitted at any time prior to travel to the United States. The Department of Homeland Security recommends that travel authorization applications be submitted at least 72 hours prior to travel. Unless revoked, travel authorizations are valid for two years from the date of authorization, or until your passport expires, whichever comes first.

thank you
