<p>I believe the ‘ED Agreement’ only requires the ‘international student’ to make a commitment to their First Choice school in the US that they will enroll. </p>
<p>It does not restrict the student from applying to other schools outside outside of the US for the main reason that there is no guarantee that each and every international student will get an US Student Visa to study in the US. Visas has been rejected for many students in recent times for various reasons. No international student can afford to jeopardize his admission offer from other top schools in UK and other countries.</p>
<p>CCers should understand that it is not unethical or illegal for an international student to keep offers from both Oxford and Columbia and make a decision to enroll at a later stage.</p>
