Passports, Customs, and TSA: How the Government Handles Your Trip
Key takeaways
- Passports are issued by the State Department, which issued a record 27.3 million in fiscal 2025. Routine processing took about four to six weeks, and most adults can renew online.
- Since May 7, 2025, a REAL ID or passport is needed to board domestic flights, and TSA screened a record 3.1 million people on November 30, 2025.
- The State Department rates countries from level 1 to 4 for safety, and embassies help Americans abroad, but they cannot get anyone out of a foreign jail.
- Customs and Border Protection inspects travelers returning home. Each traveler can usually bring back 800 dollars in goods duty free and must declare more than 10,000 dollars in cash.
- Global Entry and TSA PreCheck let vetted travelers move faster for a fee.
- Unpaid child support or large tax debts can block a passport, and U.S. passports are not valid for travel to North Korea without special permission.
A trip abroad brings you into contact with at least four federal agencies: the State Department, which issues your passport and helps you overseas, the Transportation Security Administration at the airport, Customs and Border Protection when you return, and sometimes the Agriculture Department, which inspects food and plants.
This guide walks through each step and explains the rules and the recent changes.
The State Department issues travel advisories for every country on a scale from level 1, exercise normal precautions, to level 4, do not travel. Travelers can enroll in its Smart Traveler Enrollment Program to get alerts and be contacted in an emergency. Other countries set their own entry rules, and many require visas or online travel authorizations, while Europe began a new digital entry and exit system in 2025. Travel to Cuba is restricted by Treasury sanctions rules, and the CDC posts health notices and vaccine advice.
The State Department can deny or revoke a passport for child support debt over 2,500 dollars, seriously delinquent federal taxes above about 65,000 dollars, some criminal matters, and national security reasons, and U.S. passports are invalid for travel to North Korea without special permission. People on government watchlists may be barred from flying. Since 2025 passports must show sex at birth. Debates continue over border device searches, facial recognition at airports, the cost and wait for passports, and travel restrictions on specific countries.
The Transportation Security Administration screens passengers and bags at about 430 airports. Since May 7, 2025, travelers 18 and older need a REAL ID compliant license, a passport, or another accepted ID to board domestic flights. In July 2025 TSA stopped requiring most travelers to remove their shoes, and on November 30, 2025, it screened a record 3.1 million people in one day. TSA PreCheck members use faster lanes, and liquids in carry-on bags are generally limited to containers of 3.4 ounces.
Returning travelers pass through Customs and Border Protection, which checks passports and declarations and can inspect bags. Each traveler can usually bring back 800 dollars worth of goods duty free, with lower limits for alcohol and tobacco, and must report more than 10,000 dollars in cash or similar instruments. Agriculture inspectors check for fruit, meat, and plants that could carry pests or disease. Global Entry members and users of the free Mobile Passport Control app often move faster. Officers may search phones and laptops at the border without a warrant, a practice courts are still sorting out.
U.S. embassies and consulates help Americans who lose passports, are victims of crime, get sick, or are arrested, and they can issue emergency passports, provide lists of local lawyers and doctors, contact family, and in some cases arrange emergency loans. They cannot pay legal bills, get anyone out of jail, or override local laws, which apply to Americans abroad. In crises the department may help evacuate citizens, usually on commercial or charter flights that travelers repay. For Americans taken hostage or wrongfully detained, a special presidential envoy leads efforts to free them.
Passports are issued by the State Department's Bureau of Consular Affairs, which issued a record 27.3 million in fiscal 2025. First-time applicants apply in person at a post office or other acceptance facility, and an adult passport book cost 165 dollars. Most adults renewing a recent passport can apply online. Routine processing took four to six weeks in 2025, and expedited service two to three weeks for an extra fee. A passport card is cheaper but works only for land and sea travel to Canada, Mexico, and the Caribbean.
