12 Must-Know Facts About the USA to Fit In Like a Local

Stepping into life in the United States can feel like landing on a different planet—especially if it’s your first time. From unusual customs to unspoken social rules, American culture has its own rhythm. But don’t worry—adjusting doesn’t have to be confusing. In this guide, we’ll walk you through 12 must-know facts about the USA to help fit in like a local.

1. Tipping is Expected

In most service settings, tipping is expected and seen as respectful. At restaurants, a 15–20% tip is the standard. You’re also expected to tip rideshare drivers, barbers, hairstylists, delivery drivers, valets, hotel staff, and even tour guides. Leaving no tip may come across as rude or ungrateful.

However, if the service was poor or disrespectful, you’re not obligated to tip—use your judgment.

2. Small Talk is Part of Everyday Life

In the U.S., casual conversations with strangers are common and seen as polite. This is known as small talk. People often chat about everyday topics like the weather, local sports, or weekend plans. It’s also normal to hear questions like, “How’s it going?” or comment on something around them, like the line at a coffee shop.

At first, this might feel unfamiliar depending on your culture, but small talk is a natural part of American social life. It’s also a fun way to meet people and improve your English skills at the same time.

3. Sales Tax Isn’t Included in Prices

We love shopping in Europe because the price on the tag is exactly what you pay. In the U.S., though, it’s different. Don’t be surprised when the total at checkout is higher than the listed price. That’s because most states add sales tax during checkout—it’s rarely included on price tags.

On average, sales tax in the U.S. is around 7.1%, but this varies by state and even city. For example, California has one of the highest base rates at 7.25%, while Oregon, Delaware, New Hampshire, and Montana charge no state sales tax at all. Always calculate the local tax rate before making a big purchase!

4. Time Really Matters

Being on time matters in American culture—especially in professional environments. Punctuality is seen as a sign of respect and responsibility. Whether it’s a meeting, class, or social gathering, arriving late can leave a bad impression. Being considerate of time helps build trust and shows you value others’ schedules.

Running late? A quick text or call is appreciated.

5. Personal Space is a Cultural Norm

Americans generally value more personal space than many other cultures, especially in casual or unfamiliar settings. During conversations, they often stand farther apart and avoid unnecessary physical contact. This preference may feel distant at first, but it’s considered polite and respectful in U.S. culture.

6. Portion Sizes Are Larger

Restaurants in the U.S. often serve large meals compared to other countries. Thankfully, taking leftovers home is perfectly normal. In fact, most places will even offer a “to-go box” without you needing to ask. Many people enjoy part of their meal on-site and save the rest for later.

7. The U.S. is Incredibly Diverse—And So Are You

Roughly one in seven U.S. residents were born outside the country, making diversity a defining trait of American life. People from all over the world bring their cultures, languages, and traditions, creating a rich and welcoming environment. As an international student or visitor, you’re part of this ongoing story. You’re not alone—and with time, it becomes easier to connect with others who share similar experiences.

8. Public Transportation Varies by City

In cities like New York, Boston, and Chicago, public transportation is reliable and commonly used. However, in many other areas—including large cities like Miami—owning a car is often necessary. Public transit in the U.S. generally falls short compared to systems in Europe or Japan.

9. Healthcare is Expensive Without Insurance

In the U.S., medical care can be shockingly expensive—even for basic services. Without insurance, a simple doctor’s visit or urgent care appointment may cost hundreds of dollars. That’s why it’s important to have health insurance, even for short stays. Many universities and employers offer plans or help students find coverage. Before arriving, take time to understand what’s included and how the system works.

10. School Spirit is a Big Deal

The United States is home to many of the world’s top universities—and school pride runs deep. Students proudly wear their college colors, often sporting hoodies, hats, or backpacks with the school logo. Attending sports events, especially football and basketball games, is a big part of the student experience. These events bring the campus together and create a strong sense of community. It’s one of the best ways to fit in and enjoy your time as a student in the U.S.

11. Americans Dress Casually—But It Depends

In the U.S., people often dress very casually. You’ll see students wearing sneakers, hoodies, or gym clothes—even if they’re not going to the gym. This is called leisurewear, and Americans fully embrace it.

However, it’s important to dress appropriately for the situation. For job interviews, religious places, or formal events, wearing more professional or respectful clothing is expected. Casual clothing is fine for school and daily life—but not for every occasion.

12. Drive-Thrus Are Everywhere

Thanks to wide-open spaces and a fast-paced lifestyle, drive-thru services are a major part of American culture. You’ll find them not only at fast food restaurants but also at pharmacies, coffee shops, and even banks. Americans value efficiency, and drive-thrus make everyday errands quicker and easier—especially for people on the go.
