Things That Surprise Americans Traveling Internationally for the First Time

In the United States, tipping 18–20% at restaurants is standard practice and often a meaningful part of service workers' income. Abroad, that assumption doesn't always hold. In Japan, tipping can be seen as impolite. In many European countries, rounding up the bill or leaving a small coin is perfectly appropriate. Some countries build service charges directly into the menu price.

Before you travel, take a few minutes to look up tipping norms for your specific destination. A quick search or a travel guidebook entry can save an awkward moment — and make sure your generosity lands the way you intend it to.

The US uses Type A outlets and runs on 120V electricity. Much of the rest of the world uses different plug shapes and 220–240V systems. Plug your standard American charger into a European outlet without the right adapter or converter, and at best it won't fit — at worst, you could damage your device.

Most modern electronics (laptops, phone chargers, cameras) are dual-voltage, meaning they handle both 120V and 240V automatically — check the small print on the power brick. But you'll still need a plug adapter for the physical shape. Packing a universal travel adapter is one of those small wins that prevents a genuinely frustrating situation. Packing light for international travel covers how to bring the right gear without overstuffing your bag.

Americans have grown accustomed to tapping a card for everything from a coffee to a cab ride. In many countries — including parts of Europe, Southeast Asia, and Latin America — cash is still king for small purchases, local markets, taxis, and family-run restaurants. Some vendors simply won't accept cards.

It's worth carrying a reasonable amount of local currency at all times, especially when venturing outside major cities. ATMs are generally the most practical way to access local cash abroad, though fees vary. Learn how currency exchange works so you're not scrambling at the airport kiosk with a bad rate.

Show up for dinner at 6 p.m. in Spain and you may find an empty restaurant — locals often eat at 9 or 10 p.m. In France, lunch can be a leisurely two-hour affair. In many Asian countries, portions are smaller and meant to be shared across multiple dishes. In others, the meal arrives without the sides Americans expect as standard.

This isn't worse — it's just different. Leaning into local meal culture is genuinely one of the best parts of traveling abroad. Just adjust your expectations and your schedule, and you'll find it's one of the highlights rather than a source of frustration.

Landing abroad and opening your phone's maps app without a plan in place can result in a surprisingly large roaming charge when you get home. US carriers have different international add-on options — some include international data in their standard plans, others charge per day or per megabyte.

Before you leave, contact your carrier to understand exactly what's included. Many travelers also buy a local SIM card upon arrival for an affordable data plan. Either way, sort this out before departure rather than after. It's also worth noting that Global Entry can speed up your return through customs, which is a nice bonus after a long international flight.

Many Americans assume that a valid passport is all you need to board an international flight. In reality, many countries require your passport to be valid for at least six months beyond your travel dates — even if you're only staying a week. Some destinations require a visa obtained in advance; others offer visa-on-arrival or electronic travel authorizations that still require pre-registration.

Always verify entry requirements directly through official government sources — both the US State Department website and the destination country's official immigration authority. These rules change, and the airline or border agent enforces them strictly. Planning gaps that cause the most friction abroad covers this and other overlooked logistics worth double-checking before you fly.
