After your contract and deposit have been received by ISV, you can submit your project preferences through our Project Preference form. We make every attempt to accommodate participants, however many factors influence the project placement ISV will give you. For example, spaces on projects are limited and some projects only operate on certain dates. If you are doing academic credit or independent study, you will need to be assigned to a specific project with other academic credit or independent study participants, and if you are traveling with a friend, this will also affect your placement! Therefore, we cannot guarantee that you will be placed on the projects that you most prefer.
