3. Your parcel is On Route/In Transit to USA Chicago. It can take from 15 to 35 days and sometime more to be deliver.

4. Please take into consideration that this time of year is the most busiest time for every Post Office in the World, so mail is definitely slow.

5. You should continue to track your parcel on the USPS site for any new movement.

Hope this help.
