We sent in our OWP and PR sponsorship paperwork and they received it (we are inland) on August 16. My sponsor received an AOR (Acknowledgement of Receipt) on September 13. I received my OWP on November 20th.
We have yet to receive the linking information, however I was able to link my paperwork to a GCKey online. It was kind of tough, but I finally got it to link by placing a space after every entry. Sounds weird, I know but it worked! I think I used the App number and my UCI number to link. Someone else told me about the space after each entry and it finally worked for me. If you applied for your OWP before it expired I would think you would still be "in status". I also encourage you to check with your local MP's office for assistance. Ours has been HUGELY helpful!
