"Absent a reasonable legal justification not to redeem Tether Tokens, and provided that you are a fully verified customer of Tether, your Tether Tokens are freely redeemable...
Furthermore, residents of certain U.S. states are not permitted to be customers of Tether; are not permitted to cause Tethers to be issued or redeemed; and, are not permitted to hold Tether Tokens. Beginning on January 1, 2018, Tether Tokens will no longer be issued to U.S. Persons."
So if you hold Tether Tokens but are not a "customer", you have no claim to be paid. I suppose Tether customers (whoever they may be) might be willing to pay you dollars for your coins, but there's no reason for them to give you 1:1, for sure.
This is only true if there really is a USD for every USDT out there in the market. If it turns out to be a fake, the whole thing comes crashing down and becomes unpegged as soon as growth stops, i.e. as soon as we run out of "greater fools" to keep supplying sufficient inflow of USD for everyone that's trying to cash out.
