So, I'm trying to register my game here, which apparently means I'll have to create accounts in twelve different systems and jump through a thousand hoops, but I'm sure I'll get there. Before I do something foolish, however, I'd like to know if my payment options are in any way tied to my selected country of residence. I know SE overcharges if you want to pay in the good old EUR, so I'd like to pay in GBP or even USD if possible.

When creating a Square Enix ID (why is this separate from Square Enix Members?), it says I cannot change my country once the registration is complete, so I want to get this right.

edit: Nevermind, I was able to find the information I desired. Basically, always lie you're from the UK if you play from the EU region.
