由于USCIS现有大量的案件需要处理，而导致不少申请人还没收到其案件的receipt。之
前我们为大家报道了USCIS对一系列有关问题的解答，现在USCIS继续对一些申请人所关
注的问题作答，以下为详细内容：
1. FIFO Policy? - Is USCIS following the “First In First Out” policy in
receipting applications? Many people have commented that their application
arrived at USCIS specifically on July 2 or 3, but that they still do not
have a receipt notice. Can you please explain why that may be? How can
someone know if his case was not lost?
* Response: We understand that USCIS’ policy still is to work
