很多人申请 I-589 庇护，I-765 工卡，I-131 AP或旅行证，I-730 庇护家属后，每天都习惯性地点开 USCIS 的 Case Status Online ，或者 Case Tracker 查状态。
USCIS案件状态绝大多数就是字面意思，没有那么多玄机。 而且大字标题状态下面都有一段更详细的英文说明。
可是，偶尔申请者看完后，还是不太明白自己的状态究竟是什么意思。而且也确实有一些状态，乍一看没事，实则已经有所变化。或者看似有喜，其实可能只是平平无奇。
以下是我这么多年来，实战中总结出的 USCIS案件状态解释 ，希望对你有所帮助。由于移民局经常不时更新系统，加入新状态，如有遗漏，也欢迎指出补充。
小知识点：有人问，为什么这些状态的大小写看起来这么奇怪？其实原因很简单，这些状态并不是「句子」，而是 Title Case 的写法。所以大部分词的首字母都会大写，小部分维持小写。
预先假释文件（AP） 已制作。
AP已经做好了，可以出境使用。
详细说明：On [date], we produced your Advance Parole Document for your Form I-131, Application for Travel Documents, Parole Documents, and Arrival/Departure Records, Receipt Number [receipt number]. We will mail your document to your address of record and you should receive it shortly. If you have moved since you filed your form, go to www.uscis.gov/addresschange to give us your new address as soon as possible. If you have not received your document in 30 days, you may submit a case inquiry with USCIS at www.uscis.gov/e-request.
比较宽泛的状态，说明你的案子还没有最终决定。等候庇护面谈时，也有可能从 Next Step Is an Interview 突然变成此状态。也常见于庇护面谈后仍然没有结果。但庇护面谈后未能通过， 发出NOID 时，也可能会出现这个状态。与 Decision Is Pending 状态雷同。

有几个可能性：1. 你主动撤回案件了。2. 也有可能是移民局以其他理由终止你的案件。3. 也有可能是移民局 将你的案件转交移民法庭 。
