这似乎是对所有州都是如此，请参见网站：

U.S. Permanent ReResidents and other eligible noncitizens

A lawful permanent resident (LPR) is a noncitizen who is legally permitted to live and work in the United States permanently. Other eligible noncitizens:
。。。。。
Persons paroled into the U.S. for at least one year must provide evidence (such as having filed a valid permanent resident application) from the DHS that they are in the U.S. for other than a temporary purpose and intend to become a citizen or permanent resident.
Not enough information. If the student said she was an eligible noncitizen but provided either no A-Number or an illegible or invalid one, the match won’t be attempted. Instead, the student will receive a C code and a comment stating that there’s a question about the A-Number and directing her to provide the school with documentation of her eligibility. Compare the document with the SAR/ISIR; if appropriate, the student should correct the A-Number and resubmit it so that the match can be conducted.
Note that the same will apply to citizens of the Marshall Islands, the Federated States of Micronesia, and Palau because such students won’t have A-Numbers to report. However, these students aren’t required to provide proof of eligible noncitizen status.
▼ Status not confirmed. If the match was conducted but didn’t confirm the student’s status, the discrepancy must be resolved before you pay him. (First make sure that his alien registration number and date of birth are correct.) To confirm he is eligible for FSA funds, his record will have to pass through a subsequent process called secondary confirmation.

使用AP入境虽然花时间长一点，但非常简单。其实就是在AP和I-94上添上AOS印章里的内容，移民官忙，你不忙。
