If you've started looking into Trusted Traveler Programs (TTP), you've probably run into three names again and again: Global Entry, NEXUS, and SENTRI. They're all run by U.S. Customs and Border Protection (CBP), they all speed up your border crossings, and they all require an interview at an enrollment center. But they are not the same program, and choosing the right one can save you money and a lot of waiting.
This guide breaks down what each program does, who it's for, and how to actually land an interview appointment once you've decided.
The Quick Answer
- Global Entry — Best for most international air travelers. Expedited U.S. entry by air, and it includes TSA PreCheck®.
- NEXUS — Best if you regularly cross the U.S.–Canada border (land, air, or sea). It's also the cheapest option.
- SENTRI — Best if you frequently drive across the U.S.–Mexico land border.
Global Entry
Global Entry is the most popular Trusted Traveler Program, and for good reason. It's built around international air travel, letting approved members skip the regular passport lines and use expedited kiosks or eGates when arriving in the United States.
The biggest bonus: Global Entry membership includes TSA PreCheck® at no extra cost, so you also get faster security screening on domestic flights. If you fly internationally even once or twice a year, Global Entry usually pays for itself in saved time and stress.
- Best for: International air travelers
- Includes TSA PreCheck®: Yes
- Membership length: 5 years
NEXUS
NEXUS is a joint U.S.–Canada program designed for travelers who cross the northern border often. It works across land, air, and sea crossings between the two countries, using dedicated NEXUS lanes and kiosks.
Here's the part most people miss: NEXUS is typically the least expensive Trusted Traveler Program, and NEXUS members also receive Global Entry and TSA PreCheck® benefits. If you spend any real time crossing into Canada, NEXUS can be the best value of the three.
- Best for: Frequent U.S.–Canada travelers
- Includes Global Entry & TSA PreCheck®: Yes
- Membership length: 5 years
SENTRI
SENTRI focuses on the U.S.–Mexico border. It's aimed at travelers who drive across the southern land border regularly and want to use the dedicated SENTRI lanes for faster vehicle crossings.
Like NEXUS, SENTRI membership also includes Global Entry and TSA PreCheck® benefits, so even though it's geared toward land crossings, you still get expedited air travel perks.
- Best for: Frequent U.S.–Mexico land-border drivers
- Includes Global Entry & TSA PreCheck®: Yes
- Membership length: 5 years
How to Choose
Start with where you actually travel:
- Mostly international flights? Go with Global Entry.
- Regular trips to or from Canada? NEXUS gives you the broadest coverage for the lowest price.
- Frequent drives into Mexico? SENTRI is built for you.
Because NEXUS and SENTRI both bundle in Global Entry benefits, frequent border-crossers often get more value from those programs than from Global Entry alone.
The Real Bottleneck: Getting an Interview
No matter which program you choose, the application process ends the same way — with a required interview at an enrollment center. And that's where most people get stuck. Conditional approval can come through in days, but open interview slots at popular enrollment centers are often booked out for months.
The good news is that appointments open up constantly as other applicants reschedule or cancel. The catch is that those openings can disappear within minutes. Refreshing the official scheduler by hand, day after day, is exhausting and easy to lose to someone faster.
That's exactly the problem TTP Appointments solves. We continuously monitor enrollment center availability for Global Entry, NEXUS, and SENTRI, and send you an instant email or SMS alert the moment a slot opens at a location you care about — so you can jump in and book before it's gone.
Bottom Line
Pick the program that matches your travel patterns: Global Entry for flyers, NEXUS for the Canada crowd, SENTRI for the Mexico land border. Then let appointment alerts handle the hardest part — actually getting in for your interview.
