回复：回复：If he is attending school, COS to F-1 - 回复：求EB1A 推荐信 模板 和H

多谢， 为什么H4上的有效期给的是后年， 也就是我的工作有效期？ 是写错了？如错了， 不改行了？ 

-When the IO approved the H4, he/she did not think that much, but your kid's H4 status will be ended automatically when he/she reaches 21 years old no matter whether the H4 I-94 expires or not. So, your child needs to change his/her H4 status to F1 or other non-immigration status before he/she reaches 21.
