这个同事是老美吧？公立学校合法读书需要有身份， 包括绿卡公民还有一些签证比如f-2, h-4 等， 旅游签证不行。

那学校不收国际生

charter school. 忘掉吧.

估计没有考虑身份的问题。如果您有工作签证或者绿卡可以考虑。

来自官网：
It is required that all applications for students accepted by NC charter schools be from parents who are currently legal residents of NC. It is insufficient that the parent intends to move here at some point in the future. The domiciliary must be in place at the time of the student application in order for that particular application to gain consideration in the charter school lottery and/or admissions process.

只接受现在父母是NC州居民的孩子，并且入读该学校还有抽签的过程，在每年的三月完成该抽签。官网提到之后也是可以申请的但是推荐在那之前完成申请。
