- You could send in passport, get COPR, then send it back to invalidate COPR after you notify them of marriage like I did (they'll ask for your passport back).
- Or you could notify them Dec 10. You don't need to have the marriage certificate on-hand at that time. By the time they reply and ask for all the docs (including the MC) you'd have received it.
You'd be asked to redo them.What if your medicals expire by then ??
