Got a letter from CIS regarding the filing of I-765(working card),statement shows that the application has been denied due to approval of I-485. However I haven't receive any inform from CIS concerning I-140 and I-485, even no more information based on the web case status checking. I file I-140 and I-485 concurrently a year ago. Is this possible a mistake from CIS, or it has been approved, just without update the online status? Any one has same experience?
thanks
