@jman25 I've called them to ask about the CoPR. Yes,
@daredevil1212 was correct, it will be
mailed to the address we've indicated on the reply email. The mail consists of the CoPR letter and some instructions like 2 digital photos and etc that we need to send by mail on the address they will be providing. Since you've confirmed your telephone interview, it will still proceed regardless if you have the mailed CoPR or not (just tell the interviewer if you don't have it).
When I called them, they confirmed that they mailed it to my address last Dec 7, so I will check my mailbox everyday
It's really a cool initiative if this will be the process. Congrats to all of us
