As someone that was not born in the USA and never lived there. I'm thinking of moving to the US for a few years (4 or 5) to visit family and get a green card only not interested in citizenship.. im wondering if there is some way I can keep most of my wealth in a trust or foundation so it can be accumulating dividends for 4 or 5 years . It would have to be legitimate and something that the IRS would be ok with because I don't want to pass them off (they have guns)
