您描述的情况,多数学校会按照domestic学生算的。但排名靠前的一些学校,处理方法会有不同,比如Peddie School,这是学校官网的说明:https://www.peddie.org/admission/apply/international-applicants
At Peddie, you are considered an international student if you require an F-1 student visa to study in the United States and you will need a Form I-20 from Peddie or your family’s primary residence is outside of the United States (regardless of citizenship or visa status). 这种情况这三位学生就算国际生了。
