1. After submission of application Opus says initiated for quite a while before it automatically goes away. Unless u receive an email explicitly stating something is missing, don't worry too much.
2. Email delivery failure: I had a similar issue once and later found out that it was because she is being bombarded with emails and her email inbox was full. Give them a call ASAP to finalize the stuff would be my recommendation.
3. International wire transfer: communications is not yet updated with the message as promised on the admitted students website. But if you click on "finance: view account" and then click on "payment options" it shows the international wire transfer details to be used.
Overall opus is badly maintained and hardly updated. I received admissions confirmation on Friday but opus still says "your admission decision is not yet available". So I wouldn't worry too much about opus.
