The Global Entry Program allows travelers using major US airports to re-enter the country using fast lanes regardless of where they boarded their flight. This means that if you flew into the USA from any country in the world you can fast track US Immigration and Customs using the Global Entry kiosks. Global Entry membership is issued to pre-approved low risk travelers aged 14 or over.
If you already hold a NEXUS or SENTRI card and you are a U.S. Citizens or Permanent Residents in the United States, you will qualify for membership to the Global Entry Program.
Your Global Entry membership will have the same expiration date as your current SENTRI or NEXUS card. Global Entry does not require a card like NEXUS or SENTRI, when you are approved for Global Entry you can use the designated kiosks at any airport using your passport or permanent resident card. You must however have a machine-readable PR card to qualify.
