Well as someone whoes has bank in Tokyo, I find it's difficult to invest in US stocks without paying withholding taxes. Where do other international investors like ones from Singapore, Hong Kong invest? And what vehicles they use for minimizing taxes as an international investors. I've USD cash in bank, so if USD falls in value my wealth is erroded overnight. Can someone suggest what I should be doing?
