If you are arriving from an international trip, understanding how long processing may take can help you plan airport transfers, connecting flights, and arrival schedules more accurately. While some travelers move through customs in less than 30 minutes, others may experience longer waits due to passenger volume, document checks, baggage delays, or additional inspections.
Quick Answer
Getting through typically takes 15 to 60 minutes, but can be longer during busy travel times.
Typical Timeline
- Light traffic: 15–30 minutes
- Average: 30–60 minutes
- Busy periods: 1+ hour
What Affects Processing Time
- Airport size and traffic
- Number of international arrivals
- Staffing levels
- Documentation readiness
What Takes the Longest During Customs Processing?
Many travelers assume that speaking with a customs officer takes the longest amount of time. In reality, waiting in line is often the biggest factor affecting the overall process.
The most time-consuming parts of processing may include:
• waiting for passport control
• collecting checked luggage
• standing in customs inspection lines
• additional document reviews
• secondary inspections
• agricultural or restricted item screening
At busy international airports, the actual interaction with customs officers is often completed in only a few minutes once travelers reach the inspection area.
Ways to Get Through Faster
- Have documents ready
- Use Global Entry if available
- Fill out forms in advance
How Global Entry Can Reduce Wait Times
Global Entry is a trusted traveler program that allows pre-approved travelers to use expedited processing when entering the United States. Instead of waiting in standard passport control lines, eligible travelers may use automated kiosks or designated entry lanes.
While Global Entry does not eliminate all customs procedures, it can significantly reduce overall processing times at many major international airports. Frequent international travelers often find that the program saves considerable time throughout the year.
What If You Have a Connecting Flight?
Travelers with international connections often need to clear customs before continuing to their next flight, especially when entering the United States.
Because customs lines can sometimes be unpredictable, many airlines recommend allowing:
- at least 2 hours for international connections
- even longer during busy travel periods
Missing a connecting flight because of customs delays is more common than many travelers expect, particularly at large international airports during peak travel seasons.
Why It May Take Longer
These lines can become much longer during busy international travel periods, especially when several overseas flights arrive around the same time.
Longer wait times are often caused by:
- High passenger volume
- Additional security screening
- Missing or incomplete documents
- delayed baggage delivery
- staffing shortages
- agricultural or customs inspections
- Sometimes travelers spend more time waiting for checked luggage than actually speaking with customs officers. When baggage delivery is delayed after a large international arrival, customs lines can back up very quickly as hundreds of passengers enter the inspection area at once.
Why Customs Wait Times Vary
The wait times depend on several factors, including international passenger volume, airport staffing, document checks, and security inspections. In addition, holidays, delayed flights, and additional screenings may increase the amount of time needed before leaving the airport.
Customs vs Immigration: What Is the Difference?
Many travelers use the terms “customs” and “immigration” interchangeably, but they are actually different parts of the arrival process.
Immigration usually happens first and focuses on:
- verifying identity
- reviewing passports and visas
- confirming permission to enter the country
Customs happens afterward and focuses more on:
- baggage inspections
- declaration forms
- restricted or taxable items entering the country
At some airports, the entire process feels combined, which is why many travelers simply refer to all of it as “going through customs.”

What Happens During a Secondary Inspection?
Most travelers pass through customs without any issues. However, some passengers may be selected for additional screening known as a secondary inspection.
During this process, officers may ask additional questions, inspect baggage more thoroughly, review travel documents, or verify declarations. Being selected for a secondary inspection does not automatically mean a traveler has done anything wrong. In many cases, inspections are random or conducted to verify specific information.
Secondary inspections can add significant time to the arrival process, which is one reason customs wait times vary so much from one traveler to another.
