What does 'residing abroad' mean? In sounds like a bit of an oxymoron, how can you reside in a country you're not in, right? Perhaps you legally reside in a country you're not physically in? Or you moved such that you established residency in a new country? Or do you have no legal residency?

In the first case, I would guess you're not permitted to move accounts, because your country of residence hasn't changed. It depends on the terms of service though.

In the second case, surely -- you reside in a country that has lower fees, like any other resident there.

In the last case, I really don't know! I've been there for a few months while waiting for paperwork. I left my accounts as-is to avoid problems.

e.g. I immigrated to Vietnam and moved my Steam account. I kept all purchases and all history. I provided my new address, and get the regional lower fees. Same with Netflix.
