回複：急需幫助

我拿HI，2007年2月交的485，手印也蓋了。我想回國工作，我兒子想在美國讀高中，請問，如果我回國，申請移民就失效了，對吧？
-Yes, unless you find a U.S. employer to support your GC application and you will come back to work for the employer after you get the green card.

我兒子怎麽樣合法留在美國讀中學， 多謝大家幫助！
-Your son needs to get an F1 status if he did not file I-485 yet (he can be F1 status only for one year in a public high school ). If he has filed I-485 and your green card application is invalid, your son's status will be big problem in u.S.
