The impression is that Neteler is deliberately declining and looking for good excuses not to pay Americans.
If EFTs to another country are no problem, why do Americans requesting same to a bank in another country have to provide other proof of foreign residence? There is no processing problem here. But it looks like there is a "agreement problem."
That is, it appears like NT has made an agreement with the US DoJ NOT to pay Americans, even if they live in another country, without going through a few hoops. The hoops being placed so as not to offend the country in which the US citizen resides, by being drawn into a specifically American thrust.
That thrust seems to have little or nothing to do with money laundering, but a concerted effort by the federal govt to dry up most online gambling by going after key selected players on the interntional online betting scene. And having the bettors lose money when books close or processors are under restraint is apparently a good way to do that.
