USCIC envelope has 3 parts:
1 adress
2 red rectangular area on the left.
3 small area of vertical lines on the top.
4: big area of vertical lines ( bar code) on the bottom.
Which part is you mean USCIS label? Or I just cut the whole front of USCIS envelope.
-Then, paste the entire information surface of the USCIS evenlop on the EMS envelop and put all your documents in the EMS envelop and give the whole packet to the post-man. Then, ask the post-man to give you the tracking number.
