我正在为LP申请回美证，她08年入美时H4，现在是AOS，我参考您写的"闲话 AP (I-131) 和 EAD (I-765)"，可是关于"Class of Admission"，我查阅了其他移民网站的解释，
Class of Admission Defined by USCIS
Posted Mar 19, 2004
We have recently had a number of clients, as well as MurthyDotCom and MurthyBulletin readers, ask us what the USCIS means by the term "Class of Admission" on the new Form I-131, Application for Travel Document. The USCIS has confirmed that they are seeking the applicant's current immigration status. They are not looking for the status at first or most recent entry to the U.S., if different from the current status. For example, if a person entered the U.S. through a Port of Entry and was granted F-1 status, but later changed his or her status to H1B from within the U.S., the correct answer on the form for Class of Admission is H1B.
这和你在文章中写的不同
3. Class of Admission ()
问的是入境时的身份，答案请参考下面的提示。
[Student] - F1
[Exchange Scholar] - J1
[Temporary Worker] - H1
[Visitor] - B-2, F2, J2, H4
[Parolee] - AP
[PR] - GC（申请 RP）
您能否在确认一下，我LP的I-131中class of admission到底是AOS还是H4?
谢谢！
