Here's a thought. If you are having an influx of new tenants on student visas, is there one school nearby or multiple schools? You might try and work with the schools where these students will be attending.
Also, are they all speaking one language as their first language, or is it multiple languages?
A suggestion might that once you know the answer to the second question that you work with the local schools to come up with a one-pager in maybe more than one language that you could give to the students when you have the meeting. You could outline expectations, etc. I am not suggesting it have the force of a legal document, just kind of a friendly 'welcome letter' tone.
I wouldn't doubt for many of the students it is their first time abroad and the more you do to reach out and communicate with them, the better the experience it will be for all. It wouldn't be unheard of for the students, at the end of their time at the school and at your property, to invite you to visit them in their home countries. From personal experience, when you later take such a trip, the hospitality of the parents is off the charts because you have taken care of their children (whom they were probably hesitant to let travel overseas anyway.)
