It is up to the board's discretion to decide. Sometimes it may be a matter of a particular technology that may not be available at a particular institution. If the institution is remote, for example, they may not have particular access to video conference there. In that case, it just wouldn't be permissible. Wherever possible, the board does try to make accommodations to suit the victim's preference.
