“When in Rome, do as the Romans do.”

Perhaps the first and still the best advice on how to avoid culture shock when traveling and getting to know different cultures.

Interacting with clients or colleagues in different countries requires respect for some subtle and not so subtle cultural differences between U.S. and foreign business practices. Monster.com and Business Insider have compiled a list of the best practices and interesting examples from some of the most popular cities for business travel.

So whether you’re a frequent business traveler, on your first company trip abroad, or a seasoned expatriate, here are some ways you can be respectful of your destination’s culture.

Greetings: Learning how to greet someone in a foreign country is a crucial part of conducting business travel abroad. Think of how embarrassed you’d be if you held your hand out to someone who was expecting a bow or if you addressed someone by their first name who wanted to be addressed by their last name? When in doubt, use a person’s title and last name until they invite you to use their first name and always bring a stack of business cards with you. While business card usage may be declining in the U.S. since the proliferation of the smartphone, in many countries you won’t be taken seriously if you don’t have a business card to give someone when you greet. In parts of the Middle East, you should never use your left hand when you offer someone a business card, while in many Asian countries, you should always use both hands.

Gifts: In many countries, it is polite to give small gifts when meeting someone, but avoid giving overly expensive gifts that may make someone feel awkward if they don’t reciprocate. Depending on where you’re going, gifts in business may be expected in some countries (example: Japan), and could be considered a bribe in others (example: China). In Japan, you should never give a company or individual a set of four or nine of anything, as these numbers are unlucky in Japanese culture. In China, you should avoid wrapping gifts in white or green paper, as they are considered unlucky colors.

Clothing: If you’re not wearing appropriate clothing, you risk making a negative first impression, which could set the tone for how you’ll be perceived through the duration of your trip. When in doubt, it’s always best to dress conservatively, and keep the standards for international business attire top of mind. The aloha shirt, while considered casual attire in the mainland United States, is considered acceptable business wear in Hawaii, where it is well-suited to that state’s warm and humid climate. Even if you work in an industry where casual dress is the norm it may not be the norm in the country you’re visiting. For example, work attire in Dubai tends to be quite formal, and women should dress modestly, covering shoulders, upper arms and knees.

Dining: Good manners are prized in any dining situation, but if don’t know your country’s dining etiquette, it’s easy to commit a dining faux pas. In Sri Lanka, it is generally not acceptable to drink or smoke in front of your boss. Take Japan- did you know when pouring a drink from the shared sake at the table, you should always serve others and never yourself? Your host, or someone else at the table, will fill your glass for you. Also, when dining in Japan don’t assume you’ll be seated at a table with chairs. Instead, expect to be seated on the tatami, a reed-like mat inset in the top part of the floor.

Personal Space: Unlike the U.S., in many countries “close talkers” are not considered an invasion of personal space and moving away may actually be interpreted as rejection. For example, if you’re having a conversation with your associate in Brazil, don’t be alarmed if they’re standing closer than you would like. If it makes you uncomfortable, try to keep your cool- in most cases, no one is trying to make you feel uneasy and this is simply how they’re used to communicating.

Punctuality: Rule of thumb: play it safe and be on time, no matter your destination. Maintaining punctuality is one of the easiest and most painless ways to make a good impression without a lot of effort. Yes, in some cultures, it’s not expected to be on time, but wouldn’t you rather not risk it? If your meeting does get a late start, take a relaxed view, especially if you’re someplace like Argentina. While punctuality is considered a virtue in Australia and New Zealanders arrive early, meetings often start late in South America.
