• Small talk is common in the U.S., and phrases like "How are you?" are often used as casual greetings.

Arriving in the U.S. is exciting. You're in a new place with a lot to learn. Some parts of American culture, though, may feel unfamiliar, such as tipping or the cost of health care. Culture shock is common when you're adjusting to a new country, but knowing a few cultural norms can make the adjustment easier and help you feel more comfortable.

Here are 10 things that often surprise international students about life in the U.S. These are general patterns, so they won't apply everywhere, but they're a useful starting point.

10 Things International Students Should Know About American Culture

American etiquette and daily life often come with unwritten rules that may take time to understand. The points below cover common situations international students may encounter, from how to greet someone to how the healthcare system works.

1. Americans Are Friendly, and Small Talk Is Normal

Americans are generally warm and comfortable making small talk. Short conversations about the weather, weekend plans, or sports with classmates, cashiers, or strangers are completely normal and considered friendly.

When someone asks, "How are you?" they're usually offering a greeting, not asking for a real answer. The expected response is something short like "Good, thanks. You?" The same applies to phrases like "How's it going?" or "What's up?"

For students from cultures where talking to strangers feels unusual, this may take some getting used to. Friendly conversation doesn't always mean someone wants to become close friends right away. Friendships usually develop over time.

Tip: Join in when you feel comfortable. Small talk is an easy way to practice your English and get used to everyday conversations.

2. Communication Is Direct, and Personal Space Matters

Americans tend to say what they mean. They share opinions openly, say "no" without long explanations, and expect eye contact in conversation. In professional settings especially, being clear and specific is valued. This can feel different if you're used to a more indirect communication style.

Personal space matters as well. People usually leave some distance between themselves when talking, especially with someone they don't know well. Unwanted touching or standing very close may make someone uncomfortable.

For international students from high-context cultures, where what's left unsaid matters as much as what's said, this directness may feel unfamiliar at first. Over time, it usually becomes easier to understand and respond in the same way.

Tip: Don't be afraid to ask clear questions or express your opinion respectfully. Direct communication is common in the U.S., and it usually isn't considered rude.

3. Independence and Individualism Run Deep

U.S. culture places a high value on individual achievement, personal freedom, and self-reliance. People often move out of their family home young, make their own decisions about career and lifestyle, and are expected to advocate for themselves in most situations.

For international students, this can mean managing your own schedule, contacting a professor when you need help, or asking for accommodations yourself. Support is available, but you may need to take the first step and ask for it.

If you come from a culture where family or community plays a larger role in decision-making, this may feel different at first. Asking for help is still completely normal. In many settings, knowing when to reach out is an important part of being independent.

Tip: Self-advocacy is a skill that's expected and respected in the U.S. If you need help from a professor, advisor, or doctor, ask clearly and directly.

4. Punctuality Is Taken Seriously

Being on time is generally important in the U.S., especially for classes, appointments, interviews, and meetings. Arriving late without letting someone know may be seen as disrespectful.

For formal meetings or interviews, arriving a few minutes early is usually a good idea. If you're running late, send a message as soon as you can. You should also treat assignment deadlines as firm unless your professor tells you otherwise or approves an extension.

If you come from a culture where time is more flexible and relationships take priority over schedules, this can be an adjustment. Using a calendar or setting reminders can make it easier to stay on track.

Tip: Use your phone's calendar and set reminders. Plan to arrive on time or a few minutes early, and let people know if you expect to be late.

5. Tipping Is Expected

Tipping is commonly expected in most U.S. service settings. It's a core part of how many service workers are compensated, since base wages in hospitality and food service are often very low. Not tipping when it's expected is considered rude.

Here's a quick general guide:

Setting	Standard Tip
Sit-down restaurant	15–20% of the pre-tax bill
Bar	$1–2 per drink or 15–20% of the tab
Rideshare (Uber, Lyft)	Optional; a few dollars or around 15–20%
Food delivery	15–20% (or $3–5 minimum)
Hair salon, spa, nails	15–20%
Hotel housekeeping	$2–5 per night
Coffee shop (counter service)	Optional, but $1 is appreciated

For students from countries where service charges are included in the bill or tipping isn't practiced, this is one of the biggest practical surprises. Budget for it as part of the cost of eating out or using services.

Tip: Check your bill before adding a tip because some restaurants may already include a gratuity. If a payment screen suggests a tip, you can choose one of the amounts or enter your own.

6. Dining Is Casual, and Bills Are Often Split

Eating out in the U.S. is generally informal and social. Unlike cultures where the host or eldest person pays for everyone, Americans often split the bill, or each pays for their own, even among close friends, so don't assume one person will pay for everyone.

Restaurant portions may also be larger than you're used to. Taking leftovers home is normal, and you can simply ask for a to-go box. Servers may also check on your table several times during the meal.

Many restaurants allow separate checks, but policies vary, and some restaurants don't offer them. Payment apps may also make it easier to divide costs, but eligibility requirements vary for international students.

Tip: If you want separate checks, ask your server when you order. And don't hesitate to take your leftovers home.

7. Dress and Interactions Are Informal

Everyday dress in the U.S. is often casual. Jeans, T-shirts, and sneakers are common on college campuses and in many social settings.

Interactions may feel informal too, including conversations between students and professors. Many professors go by their first name (though it's safest to use their title until they invite otherwise), and conversations in most contexts are relaxed and easygoing.

Some situations are more formal. Job interviews, presentations, workplaces, and special events may have different dress expectations. Greetings also depend on the setting. A handshake may be appropriate in a professional setting, while a wave or simple "Nice to meet you" works well in many casual situations.

Tip: When you're unsure how to address someone, it's fine to ask what they prefer. Most people will appreciate that you asked.

8. The Classroom Expects Participation

Many U.S. college classes encourage students to participate. You may be expected to ask questions, share your opinion, or join class discussions. In some courses, participation also counts toward your grade.

Professors also hold office hours outside of class. You can use this time to ask questions or discuss your coursework. You don't have to wait until you're struggling to go.

Academic honesty is taken seriously. Plagiarism means using someone else's words or ideas without proper credit, and consequences vary by school. They may include a reduced or failing grade and, in serious cases, suspension or dismissal.

Tip: Try to prepare a question or comment before class. If you're unsure about citation rules, check your syllabus or ask your professor.

9. The U.S. Is Diverse, and Respect for Differences Is Expected

The U.S. is home to people from many different backgrounds and cultures. On college campuses, you'll likely meet people with experiences and perspectives that are different from your own. Respect for these differences is also reflected in federal civil rights laws, which protect students from certain forms of discrimination, including discrimination based on race, color, and national origin.

Avoid making assumptions or stereotypes about someone based on their identity or background. Questions that seem casual in one culture may also feel personal in another.

Your own experiences can add a valuable perspective to classroom discussions and campus life. You don't need to know every cultural norm right away. Being respectful and open to learning will help you adjust.

Tip: If you accidentally say something that makes someone uncomfortable, acknowledge it and learn from the experience.

10. Healthcare Is Expensive, So Coverage Matters

The U.S. healthcare system may work very differently from the system in your home country. Medical care can be expensive, and health insurance helps cover eligible costs based on the terms of your plan. You may still pay part of the cost through a deductible, copay, or coinsurance.

That's why health insurance matters for international students. Remember to check your school's insurance requirements. Some schools automatically enroll students in a university plan, while others allow you to submit a waiver if your alternative coverage meets their requirements.

Before you need medical care, make sure you know how your plan works. Familiarize yourself with common health insurance terms like deductible, copay, and in-network provider.

Tip: Check your school's requirements before choosing a plan and keep your insurance information accessible. ISO offers affordable plans for eligible international students in the U.S. You can also use our doctor and hospital search to find providers within your plan's network.

How to Settle Into American Culture

Settling into a new culture takes time, and everyone adjusts at a different pace. A few simple habits can help you adjust more comfortably.

• Keep an open mind: Try to understand the context behind customs that feel unfamiliar.
• Ask when you're unsure: If you don't understand a custom or expectation, it's okay to ask someone you trust.
• Get involved: Clubs, student organizations, and campus events can help you meet people and become part of your new community.
• Stay connected to home: Keep some of the routines and traditions that are important to you. Adjusting to a new culture doesn't mean giving up your own.
• Use campus support: Your international student office and other campus resources can help you with questions or challenges during your adjustment.
• Give yourself time: Some days may feel easier than others. Cultural adjustment happens gradually, and the experience is different for everyone.

Culture shock is a normal part of adjusting to a different culture. Feeling uncomfortable or homesick at times doesn't mean you made the wrong choice. Give yourself time to get used to your new surroundings.

Make the Most of Your Time in the U.S.

These 10 points give you a starting point for understanding American culture, but getting comfortable takes time. Stay curious, ask questions when something is unfamiliar, and give yourself time to adjust.

Some customs that feel unusual when you first arrive may soon become part of your everyday routine. At the same time, studying in another country gives you the chance to meet new people and experience a different way of living without giving up your own culture.

As you prepare for your time in the U.S., don't forget about health coverage. You can learn more about international student insurance and explore affordable plans through ISO.

Frequently Asked Questions (FAQs)

What Topics Are Considered Too Personal to Ask About in the U.S.?

Questions about salary, weight, immigration status, or someone's family and relationship choices may feel too personal, especially when you don't know the person well. Religion and politics can also be sensitive topics depending on the setting. When you're unsure, it's usually best to let the other person decide how much they want to share.

How Can I Make American Friends as an International Student?

Start by spending time in places where you'll regularly see the same people. Clubs, student organizations, sports, and campus events are good opportunities to meet other students. Accepting casual invitations, such as getting coffee or studying together, can also help friendships develop naturally.

Do International Students Need to Celebrate American Holidays?

No. You don't have to celebrate holidays that aren't part of your own culture or traditions. Holidays such as Thanksgiving, Halloween, and the Fourth of July can still be opportunities to experience American customs if you're interested. Many students enjoy experiencing them as cultural events rather than personal celebrations.

What Common American Slang Should I Know?

You'll hear casual phrases that may not mean exactly what they seem to mean. "Sounds good" usually expresses agreement, while "What's up?" is often used as a casual greeting. "I'm good" may mean "no, thank you" when someone offers you something. "That's on me" can mean either "I'll pay" or "that was my responsibility," depending on the context.

Do International Students Need Insurance in the U.S.?

Most international students need health insurance, but the requirements depend on your visa and school. J-1 exchange visitors and accompanying J-2 dependents must maintain insurance that meets federal requirements during the exchange program. If you're an F-1 student, check your school's health insurance rules because requirements vary by institution.
