@bboczeng For workers at big tech firms, providing salary proof and opening bank accounts or brokerage accounts is not too difficult. In the past, many banks offered witnessed account opening. Later, scrutiny tightened, but some Hong Kong brokerages and Hong Kong cards are still promoting it. Besides that, there are US brokerages. Quite a few colleagues trade US stocks. I first got into US stocks because I heard my boss was trading them and made an eight-figure profit😂. From what I know, the few people who made money all pay taxes properly.
