Is it easy to make friends with locals here? Are there any prejudices or any ethnic groups who might feel uncomfortable here?
Yes if you speak French it is very easy! If not, that will limit you. I am sure there are groups who would be would be excluded but I do not know who they are. There is a sizable Lebanese community here, so Arabic speakers will also find peers - May 2020
Sort of ... it's a very international place, so one will meet people from all over the world, but one will have the most friends if one can speak French. If one doesn't speak French well, as I mentioned before, then do not expect to have many friends local or otherwise. - Feb 2020
