No, I don't. I'm a Canadian.
If you don't have a US tax id, most US broker-dealers will not take you as a prop trader. You have to go through sub-LLC.
BTW, both genesis and hold allow you to trade equities only, not future.
HongKong is too expensive to operate a prop trading firm imo.
Why don't you check with your ex-prop firm and see if they allow you to trade remote. Also check swiftrade. They might have an office in Hong Kong or Macau. I think they have office in shenzhen.
