In some cultures, pointing with an index finger, giving the “ok” sign, and other common gestures can be seen as offensive. Since you may not know which gestures could be mistaken in this way, stick to “open-handed” gestures. For instance, try using your whole hand if you need to point to something. Keep your feet on the floor, sit up straight, don’t use your arms too expressively, and otherwise keep your posture more or less conservative. This is because certain postures can be seen as offensive to others. For instance, showing your foot in some cultures is seen as a rude gesture, so you would not want to cross your legs in a way that your sole sticks out. If it becomes clear that a less formal posture is acceptable, you can follow suit. Some cultures may expect more physical contact between people when communicating than other cultures do. For example, some cultures may shake or touch hands more willingly than others.  Don’t take it as offensive if another culture is more or less physical than you are used to when communicating. The exception is if you think you are being violated or abused. If you are uncomfortable, let others know. It’s a good rule of thumb to be conservative with the way you touch people from other cultures when communicating with them. However, if they appear to use more physical contact, follow suit if you are comfortable doing so. In some cultures, looking another person in the eye when you speak is seen as a sign of honesty and interest. In other cultures, however, it may be seen as disrespectful, confrontational, or a sign of sexual interest. Conversely, some cultures think than not looking a superior person in the eye when communicating is a sign of respect. It is common for different cultures to use facial expressions differently. For instance, Americans may smile frequently, while other cultures may see excessive smiling as a sign of shallowness. When communicating with people from other cultures, you may notice that they are more expressive with their face (to show happiness, sadness, frustration, etc.) than you are used to, or you may notice that they do not show much expression at all. Much communication is non-verbal, no matter what the culture. However, you can focus on the content of what is being said, and ask questions to clarify if you need to. For instance, if someone reacts to something you say with an unexpected smile or laughter, you may need to say “Actually, I'm being I’m serious.” Some cultures may require more personal space than others. If you are communicating with people from another culture and you find they get closer to you or farther away from you than you are used to, it’s not necessarily the case that they are invading your space or trying to avoid you. Just try to follow their cues regarding personal space and communicate as best you can.
