I have to respectfully disagree here. I’ve found that games that require interpretation of words in a multilingual setting can quickly go from rollicking fun to “why do we have to take so many English tests?” Most especially when the English level of the players varies so widely,
This would include games like Dixit, Mysterium, Scrabble, and regular Codenames.
If the object is to for everyone to practice English with all players understanding that English practice is the objective then these games are fine. Codenames pictures and Dixit both work great for that. Mysterium and Telestrations would be good as more advanced practice. Regular codenames is probably one of the most difficult unless you carefully curate the word set.
For just having fun, maybe they would work okay every once in a while. But, in my experience, for players with limited vocabulary in a work situation where power dynamics can easily come into play these types of games can be more stressful than fun.
Even simple social deduction games like One Night Werewolf or The Resistance can be very difficult for young people who are not used to questioning authority figures (Considering the OP’s statement about working with international students it seems likely some of the players will be young and also that supervisors may play along.). I am not saying these types of games can’t work at all. In fact they could be a good teaching tool to introduce players to the culture of the workplace/school. (For example the Resistance can be good for showing that the boss can lie/be wrong and that it is okay to call them out on it or not follow their instructions if you have information that contradicts them) But I strongly recommend planning well and paying close attention to make sure that everyone is not too stressed out by the activity.
