女儿今年九月上大学。 现在是４８５ pending， 有H－４ Visa， 没有用过AP。
现在学校要证明身份的文件， 原文如下：
Please submit documentation of your citizenship status to our office
within 30 days of this notice. Acceptable documentation includes a
photocopy of ONE of the following:
**Both sides of your Alien Registration Card
**Your foreign Passport with valid Visa stamp
**Both sides of your I-94 document
**Certificate of Naturalization or Citizenship
**Birth certificate (if born in the United States)
**U.S. Passport
谁能说明第２， ３是什么意思吗？ 要交什么文件？
非常感谢。
