I manage and pay bills in other countries from my transfer account into any country, their maybe because its geared for western people, only go where takes cash, simple.
Good post report for all to be aware of and yes logically it will come where the funds are asked for proof of. Too many have gotten, but only have that amount for 5 years. They are definitely starting to tighten up.
