Option Trading Offshore Business

I am currently working on setting up my equity options trading business. I live in US on dependent visa and I am trading in IRA account to save tax and build my account faster. I might need to leave US sooner or later so I am exploring options of getting tax residency that will help me in saving taxes on my trading income so that I can build wealth faster. Based on posts in offshoretalk, I have narrowed down my options to Malaysia or Thailand. I know MM2H program is currently suspended so I have to wait until it reopens. I am not very sure about which business structure can help me in saving taxes in Thialand.

I am also planning to work with options broker Firstrade that accepts account opening applications from only these regions

Can experts in setting up appropriate offshore business structures provide me direction to achieve my purpose?
