想在想用EAD(跟隨家長的485已交了，再等排期），如果用了EAD，學校是否允許part time。
-If your child use EAD or enroll part-time course/load, his/her F-1 status will be invalid, but because your child has a pending I-485, it does not matter, anyway.
還有就是，如果用了ead孩子畢業後如果綠卡還沒拿到，是否合法身份在美？
-Yes as long as the I-485 is still pending or approved.
