Carol - On Tuesday the 8th, they only wanted the document showing the Negative test result and the document showing the (pre-)approval. They did not ask to see anything about the insurance (but of course I had all of that printed out just in case).

One other point - I printed everything in color so that it is more recognizable to those looking at it - I do not think this is required (I know at least a few had black and white copies and they made it through the process) but it cannot hurt if you can print the documents in color.
