Both students must flag the "I accept to be, Work or stay, with Student Guests of the same Nationality" in their profile.
When choosing your School House, find those with enough beds for both (a twin share or more rooms).
Unflag "No Conationals" to see those School Houses with students of the same nationality.
When sending your request, make sure you are applying for different beds / rooms (do not send two request for the same bed).
If your friend if he/she has already been accepted (or someone else), you can't go wrong! Choose the bed still available.
Now you School House will be able to accept both.
Let your School House know who you would like to share with your friend, an example: "Hi, I would like to share with Name and Surname please accept both of us".
You may ask for any other deatils about what they do, eat, classes, activities and so on.
If you do not have a friend to share with, and want us to find a Student Guest to share your School House with you, let us know, we will match you up.
If you prefer us to assign a School House to you, let us know, there are two disadvantages though: it is slower and matching not as precise. The process is faster if you ask, you skip the middleman; matching is improved as you can read many details about your School House.
We assist you in the background all the time, accoding to the requests you have made, we will suggest similar solutions (via email).
