If you are traveling internationally (outside the United States), you must have a passport that will not expire for at least 6 months past your travel dates and have at least 2 blank pages. If you like to travel outside the USA on a regular basis, Global Entry is the only way to go. No more standing forever in long lines at Immigration/Customs when returning to a U.S. airport. It’s well worth the cost ($100). It also automatically includes TSA Pre✓® (although Pre✓may not be recognized by airlines outside of the United States).
I remember one such slow moving line a few years ago that took well over an hour to clear. Now, in less than 5 minutes, I can be on my way after a long flight.
Currently, Global Entry is valid for 5 years. (A passport is valid for 10 years.) So really, the cost is minimal in the end while the convenience is at a maximum.
Note: If your identification or passport includes your middle name, be sure to use that when making airline reservations. It could mean the difference between getting to where you want to go and experiencing delays.
Important Reminder: If you have Global Entry, and renew your passport during the 5 year membership, you must relink it to your Trusted Traveler Account. Also, you must update if there is a change in residence.https://ttp.cbp.dhs.gov/

“Global Entry is a U.S. Customs and Border Protection (CBP) program that allows expedited clearance for pre-approved, low-risk travelers upon arrival in the United States. Members enter the United States through automatic kiosks at select airports.”
