I'm reviving this thread because of my lightbulb moment today.
Picture this, you form a US LLC, form a Barbados branch, get employed by the branch and become ordinarly resident in Barbados (no minimal stay required).
Your branch pays 5.5% down to 1% taxes depending on your revenue.
If your revenue is $500K you are already paying 3%
You send profits back to US LLC
Your single member US LLC is 100% owned by a Nevis holding company.
Your Nevis holding company distribute dividends to you in Barbados tax free.
With this setup you get everything, nearly 0% taxation, asset protection and freedom of movement.
