Many brokers outside US offers trading for US stocks. However the Phillipines broker may charge two commission (Phillipine and US).
Will you pay to two brokers commission?
You have demonstrated that you don't know the difference between commissions, stamp duty and taxes.
Assuming the broker is in the Philippines and trading US stocks, why would I pay commission to the Philippines Stock Exchange? It has nothing to do with the PSE.
Commissions are per exchange (+regulatory fees) and not by country.
