Congratulations!!!!
....I've been missing in action on this forum since I got my passport back stamped
and I see a lot has happened since then! I know you've waited a very very long time for this. Now enjoy the moment and bask in the sunshine of good news for a while!
I used Fedex and everything went REAAALLLLY smoothly! You need to call 1-800-GO-FEDEX and set up an account with them. Then print out both the labels for the CPCO part and the pre-printed return part of the journey (This can be a bit complicated, so have a fedex account rep guide you though this - they helped me with this). Then print out everything (about 6 pages in total - customs forms etc.), and you're done! Enclose everything they've asked you for, including your self-addressed and prepaid Fedex envelope and send it!
I got my passport back stamped with my COPR in 8 days! Was very quick and unexpected! Wish you the best for a similarly smooth outcome!!
Also wish all of you remaining folks waiting for their PPR the best so that they send it to you very soon!!! ....and close out "FSW" once and for all.
