无忧，最近OPT申请被转到Potomac Service Center 很正常。

被转到新服务中心的有两类。
1、已经发受理通知，但未处理完的，通知你转走。
2、新申请的，直接转走。转到了再发受理通知。
记住，如果有什么要求，除了提供case number外，还要说明转到了PSC，便于查找。

下面是官网3月28日的公告。

Potomac Service Center Now Processing Certain Form I-765 Cases


On March 28, 2016, the Lockbox began sending certain cases to the Potomac Service Center. This includes all newly filed Form I-765, Application for Employment Authorization, applications filed by F-1 and M-1 students seeking Optional Practical Training (OPT).

How You Will Be Affected

When the Lockbox sends your case to the Potomac Service Center, we will send you a notice with your receipt number. Cases sent to the Potomac Service Center will be assigned a receipt number that begins with YSC, which is the prefix used to identify Potomac Service Center filings.

The filing location and instructions for these forms will not change. Please continue to file the forms at the address listed under Where to File in the Form I-765 instructions and on the Web page.

How to Track the Status of Your Case

Check your case status online with your receipt number. You can also sign up to receive automatic case status updates by email.

If you have any questions regarding your case, submit an inquiry online using our e-Request tool or call the National Customer Service Center (NCSC) at 800-375-5283 (TYY 800-767-1833). When asking about your case status, please provide your receipt number and specify that your case was sent to the Potomac Service Center.

If we send you any notice (such as a Request for Evidence) please read the notice carefully and follow the instructions provided.

If you move while your case is pending, you must inform USCIS of your address change. You may file a change of address on our website or by calling the NCSC. It is important that you notify us of any address change as soon as possible, so that you continue to receive notifications from USCIS.

The Potomac Service Center is expecting a large number of Form I-765 student filings within the next several months as students prepare for summer employment. We appreciate your patience while the Potomac Service Center prepares for the anticipated surge in applications.

PSC地址在VA的水晶城附近。
所以凡是转过去的申请，无疑要增加一次邮寄的时间。
但如果处理速度快了，还是值得的。

那这个新的服务中心是只处理从3.28之后transfer过去的case喽？我是4.4转过去的

我是3月29号被转到Potomac，然而现在并没有任何消息，之前打电话给USCIS也只是说等着……怎么这么麻烦啊……
