您好：La Jolla Country Day School国际生有无绿卡都可以，学校官网上提示，有美国绿卡的学生，学校可以直接受理申请；没有绿卡的学生，需要通过学校指定的合作机构International Education Management, Inc. (IEM)进行申请，包括I-20表在内，机构也会一起发放给学生。由于是独代学校，寄宿家庭必须是机构来安排。
不需要有绿卡，学校可以提供 I-20. 以下是学校网上的一段，摘抄给你参考：
“All international student applicants who require an F-1 visa to attend school in the United States will need to contact International Education Management, Inc. (IEM). This includes students who currently attend a school in the U.S. on an F-1 visa. IEM will assist with all inquiries, applications and, should admission be awarded, the enrollment process. Should a student be offered admission and the offer of admission be accepted, IEM will also provide a comprehensive set of student support services such as legal guardianship, assistance with I-20 related matters, health insurance, housing and various activities.”
