Have you thought about revoking american citizenship? If you do not intend to live in the US at all, there is no point paying additional money to Uncle Sam, IMHO, since you are not receiving any socio-economic benefits from the US.
It may not be too costly for you to do so from a tax perspective, assuming that you are not a high income earner. check out the IRS website on Expatriation Tax.
