Your First International Trip: Everything You Need to Know Before You Go

Getting Your Passport and Visa Sorted

Your passport is the single most important document for international travel — without it, you're not going anywhere. If you don't have one, apply through the US Department of State well in advance; routine processing generally takes 6–8 weeks, though timelines shift seasonally. Even if your passport exists, check the expiration date carefully. Many countries require that your passport remain valid for at least six months beyond your travel dates, so a passport expiring in a few months could get you turned away at the border.

Visa requirements are separate from passport validity and vary dramatically by destination. Some countries offer Americans visa-free stays of 30–90 days; others require a visa obtained in advance through an embassy or consulate, which can involve paperwork, fees, and processing time. The US State Department's country information pages are the authoritative source — always verify entry requirements there rather than relying on travel blogs or word of mouth.

If you're traveling with children, note that minors need their own passports for international travel. The rules for applying on behalf of a minor are more involved. See our guide on international travel with kids for what families need to prepare.

Money, Cards, and Currency Abroad

Managing money overseas is simpler than it used to be, but a few missteps can be costly. Before you leave, call or message your bank and credit card company to let them know your travel dates and destinations — this prevents your card from being flagged as potentially fraudulent when a charge appears from overseas.

Foreign transaction fees — typically 1–3% of each purchase — are charged by many US cards on international transactions. If you travel frequently or have a long trip planned, it may be worth looking into a card that waives these fees (a general consideration, not a specific product endorsement). At your destination, withdrawing local currency from ATMs affiliated with major international networks is generally more reliable and safer than exchanging cash at airport kiosks, which often carry unfavorable exchange rates.

Carry a small amount of local currency in cash for situations where cards aren't accepted — rural areas, small vendors, transit systems, and tips. A mix of a credit card, debit card, and a modest cash reserve is the most resilient approach.

Navigating Customs and Immigration

Every international trip involves passing through immigration — both when you arrive at your destination and when you return to the US. At your destination, an immigration officer will check your passport, may ask about your purpose of travel and where you're staying, and stamp your entry. Answer questions honestly and concisely; there's no need to be nervous — this is routine for millions of travelers.

Returning home, US Customs and Border Protection (CBP) requires you to declare goods purchased or acquired abroad. Each US resident is entitled to an $800 duty-free exemption per trip (verify current rules at the CBP website, as these can change). Certain items — fresh produce, meats, and other agricultural products — may be prohibited or restricted entirely. When in doubt, declare it; failing to declare items can result in fines. On the aircraft home, you'll typically receive a customs declaration form to fill out before landing.

Staying Safe and Connected

Before departing, look up the US State Department's travel advisory for your destination. Advisories are ranked on a four-level scale from "Exercise Normal Precautions" to "Do Not Travel," and they also contain entry requirements, local law notes, and health information. Our guide to reading a destination's travel advisory explains exactly how to interpret these levels.

For phone and internet access, contact your US carrier before leaving to understand your international options. Roaming without an international plan can result in surprisingly large bills. A local SIM card purchased at your destination is often the most economical choice for longer trips, though this requires an unlocked phone.

Register your trip with the State Department's free STEP program (Smart Traveler Enrollment Program), which allows the nearest US embassy to contact you in an emergency and provides updates for your destination. Also make digital and physical copies of your passport, visa, and key reservation documents — store copies separately from the originals.

What to Expect at Every Stage of the Journey

International flights almost always depart from and arrive at major international airports, which are larger and more complex than typical domestic terminals. Allow extra time — most airlines recommend arriving at least three hours before an international departure. Security for international flights follows similar procedures to domestic travel, but some airports have additional screening steps.

Long-haul flights introduce realities that short domestic hops don't: time zone changes, jet lag, and extended time in a pressurized cabin. Staying hydrated, moving periodically, and adjusting your sleep schedule to your destination's time zone in the days before you leave can all help.

On the ground, give yourself grace during the adjustment period. Signage, transit systems, and everyday customs will feel unfamiliar at first — that's normal. Start with a solid trip plan built before departure, and check our international travel prep checklist to confirm you haven't missed a step.
