I moved to Germany last year for educational reasons. I love it here, and one of my favorite things is that I legitimately avoid Delta's MQD requirement

When I first changed my address I had to upload a copy of my German bank account statement. The change then processed without trouble in about a week.

I have now moved to a new address, also in Germany. I just updated my address online and was not required to upload any documentation, it was just like changing to a different US address on the Delta site.

So, should I be anticipating a demand for documentation? An account audit? Should I avoid crossing a Medallion threshold for a few weeks?

Again, I should emphasize, I do legitimately live in Germany and will for the foreseeable future. I'm not gaming the MQD requirement waiver in any way.

Thanks!
