The Charleston, SC Global Entry Enrollment Center sits at 5550 Porsche Blvd in North Charleston, on the grounds of Charleston International Airport (CHS). It's the enrollment option of choice not only for residents of North Charleston and the city of Charleston itself, but also for travelers coming from Summerville, Goose Creek, Mount Pleasant, James Island, and West Ashley. Because this was South Carolina's first dedicated Global Entry enrollment center, it also draws applicants from farther afield, including Columbia, Myrtle Beach, Hilton Head, and even southeast Georgia, since a dedicated in-state option didn't exist here before.
Once you're conditionally approved for Global Entry, this is where U.S. Customs and Border Protection (CBP) will conduct your in-person interview. Below is what to know before you go, including how to get there, what to bring, and how to beat the wait if the online scheduler shows nothing available.
No available appointments at Charleston SC?
If you've checked the Trusted Traveler Programs (TTP) scheduler and found the Charleston enrollment center fully booked out for months, you're not alone. Slots here can vanish quickly once word gets out that South Carolina finally has its own center. The good news: appointments get cancelled and rescheduled every single day, which opens up earlier slots that most applicants never see because they aren't refreshing the page around the clock.
That's exactly why savvy travelers use Snapslot to monitor the Charleston enrollment center continuously and send an SMS text the moment a cancellation opens up. Instead of manually refreshing the TTP site every few hours, you get a heads-up in real time and can jump on an earlier interview slot before anyone else grabs it.
Stop refreshing the scheduler by hand. Snapslot watches Charleston SC around the clock and texts you the instant a cancellation opens up.
Knowing the Global Entry Application Process
If you're new to Global Entry, here's the process from start to finish:
- Submit Your Application: Create a Trusted Traveler Programs (TTP) account and complete the online Global Entry application. There's a non-refundable application fee.
- Await Conditional Approval: CBP reviews your background information. This can take anywhere from a few days to several weeks, so don't book travel around a specific timeline.
- Schedule Your Interview: Once conditionally approved, you'll need to book an in-person interview at an enrollment center like Charleston SC. Appointments here fill up fast, especially since it's the only dedicated Global Entry center in the state. If nothing shows up when you check, Snapslot can alert you the moment an earlier cancellation appears, so you're not stuck waiting months.
- Attend Your Interview: Arrive on time with your documents (more on that below), and go through a short interview with a CBP officer.
- Await Final Approval: If everything checks out, you'll typically get final approval shortly after your interview, and your Global Entry card will arrive by mail.
Preparing for your interview
Show up to 5550 Porsche Blvd with the right paperwork, and the interview itself usually takes just a few minutes. Bring:
- A valid, unexpired passport, plus a second form of government-issued ID (your driver's license works). CBP's own notes for this location specifically call out that a passport and driver's license or proof of residency are required.
- Your conditional approval letter or confirmation email from the TTP portal.
- A mental (or written) list of every country you've visited in the past five years. The officer will ask about your international travel history, and it should match what's already in your application.
Treat the interview as an honesty check as much as an identity check. CBP officers are trained to notice inconsistencies between your application, your answers, and your travel history, so answer plainly and don't guess if you're unsure of an exact date. It's also worth dressing reasonably professionally. You're not required to wear a suit, but neat, presentable attire signals that you're taking the process seriously, and first impressions can smooth along a routine interview.
Getting to your appointment
The enrollment center is located at 5550 Porsche Blvd, North Charleston, SC 29418, on the Charleston International Airport campus. CBP's own guidance notes that entering this exact address into your GPS will take you directly to the building where interviews are conducted, and that signage on-site helps direct applicants to the right entrance. If you want a preview of the building before you drive out, you can check the Street View for the address ahead of time.
Parking at Charleston SC
Because the enrollment center sits on airport property, plan to use Charleston International Airport's public parking, which includes short-term garage parking and surface economy lots with a shuttle connection. Budget a few extra minutes to park and walk over, especially during weekday mornings when airport traffic is heaviest. Since this is a working CBP office and not a walk-up storefront, don't expect dedicated visitor parking right at the door. It's also worth checking the Charleston International Airport website for current parking rates and lot locations before you go.
Taking Public Transit to Charleston SC
North Charleston is served by CARTA (Charleston Area Regional Transportation Authority) buses, and CARTA operates routes connecting the airport area to downtown Charleston and surrounding neighborhoods. If you're coming from downtown Charleston, Mount Pleasant, or West Ashley without a car, check CARTA's current schedule for airport-area routes and build in extra buffer time, since bus frequency on airport routes tends to be limited compared to a major transit hub.
For travelers coming in from Summerville, Goose Creek, North Charleston's surrounding suburbs, or visiting from out of town, a rideshare like Uber or Lyft is often more reliable than public transit for hitting an exact appointment time, particularly for early-morning slots.
No available appointments?
If the TTP scheduler shows nothing open at Charleston SC, you have a few options:
- Enrollment on Arrival: If you're flying internationally into one of the limited number of participating U.S. airports, you may be able to complete your Global Entry interview on arrival instead of booking a separate appointment. Charleston International Airport is primarily a domestic hub, so check CBP's current list of Enrollment on Arrival airports before counting on this option here.
- Manually refresh the TTP site: Some applicants have had luck simply checking back on the scheduler frequently, particularly early in the morning or midweek, since that's often when cancellations get posted. One local report on the Charleston center specifically noted that if the schedule fills up, it's best to keep checking for last-minute cancellations, since persistence can pay off.
- Let Snapslot do the refreshing for you: Instead of checking manually multiple times a day, Snapslot monitors the Charleston SC enrollment center around the clock and sends you a text the moment an earlier appointment opens up, so you can book it before anyone else does.
Remember that this location does not accept walk-ins. You'll need conditional approval and a booked appointment on the TTP portal before you show up at 5550 Porsche Blvd. Bring your documents, arrive a few minutes early, and you'll likely be in and out faster than the drive itself took.
