The currency can't be changed into dollars, instead EA made it clear that all who are outside USA, & with no Origin Region for them, will be directed to the EU region.
There is only a couple of regions
Region for Europe
Region for USA
Region for UK
etc..... (France, Spain, Italy)
& for every other country out there, Asia, or Latin America, Africa, all are directed to the EU store, as it is selected to be Origin's Default prices.
Hope that helped. You can google to find other/better answers, but i think this is it.
