2. Your parcel is On Route/In transit to USA Chicago. Either your parcel is lost/misplace or USPS did not scan your parcel on arrival or did not have the time to scan your parcel yet.

3. You should contact seller as soon as possible to ask him to call China Post EMS to find out about your parcel.

4. Also E Packet to USA can from 15 to 35 days to be deliver and sometime more. This time of year is the busiest time for all Postal Office in the World and mail is slow.

Hope this help.
