The colleges need to know the details. Some cannot admit international students without knowing exactly how that student will pay for their studies.
Contact the colleges. Give them all of the information about the scholarship: the name, the sponsoring organization, the amount of money awarded to you for each year, what you need to do to have the scholarship renewed each year, and any contact person they will need to stay in touch with. Some colleges will have heard about this scholarship, or will have had previous recipients as students. If so, they will know how likely it is that you will be able to keep the scholarship for all four years.
