What is a RFE?
RFE stands for Request For Evidence. USCIS will send you a RFE when they need more information from you, such as missing or incomplete documents in your application. It doesn't mean your case will be denied or approved soon, although after long delays in security checks, a RFE may be a good sign that your case is moving again. It is very important to respond to a RFE before the deadline. On June 18, 2007, new Flexible Response Times for RFE and NOID (Notice of Intent to Deny) took effect and they are now considerably shorter than the standard 3-month timeframe. So it is more important than ever to respond to a RFE/NOID before the deadline.
