2. Both parcels have been receive by China Post EMS. Because China Post EMS site is down I can not say to you where your parcel is going to land in USA.

3. For Parcel LT510654071CN it's On Route/In Transit to USA. Parcel to USA can take between 15 to 35 days to be deliver and sometimes more.

4. For parcel LT609208830CN, it was just receive so no other tracking is available.

5. Just continue to track your parcel on the USPS site for any new movement of your parcel.

Hope this help.
