My dilemma is this: I have a foreign address as my Delta SkyMiles address but I just applied and got approved for the us based Amex delta. My foreign address is legit in the sense that I do work and live abroad for most of the year but I have a us address for credit cards bank accounts and the like. Will delta credit the signup bonuses for Amex delta and all the associated points? Has anyone had any experience with this? Thanks in advance.
