There can be two ways to look at it: a. Maybe all of them are close-minded and don’t want to mingle with anyone who does not speak their language or is from a different culture. However, the probability of this is very low. Based on my own experience of working in a multicultural environment, people are very different even though they may all belong to the same country. All of them cannot be unwelcoming. There will always be a mix- some friendly and welcoming people in the group and some reserved ones who take time to open up. You need to identify the welcoming lot and start interacting with them, probably hanging out with them during lunchtime or coffee breaks or smoke breaks. Once you get to know a couple of people, sooner than later, it will have a cascading effect and you will be comfortable with the rest of them. b. Maybe most of them are friendly and welcoming, but you have never taken the initiative to talk or interact with them. If you are the only person from another nationality, you will need to make a little more effort to get to know other people. There is always an initial reluctance when people don’t know your background and so they may be naturally cautious. However, if you show interest in talking to them and being cooperative, sooner than later, you will find yourself surrounded by many new friends
