If I fill out a W-7 as a non-American to get an ITIN - Is that then enough to open a credit card with say Navy Federal prior to even getting an address in the USA? I'd like to have all my ducks in a row prior to even arriving if possible.

I believe so but that's not really an immigration question but a banking question. I would recommend calling a couple of banks.
