>Singaporean citizens of Chinese heritage tend to enjoy preferred treatment over their Malay and Indian counterparts. Examples of overt discrimination include employment ads specifying that someone must be of Chinese origin to apply.

Not to defend this, but I expect to see this among smaller employers in US tech hubs in the future.

Anecdotally, I know two PRC nationals who spent two years in Singapore working for employers that discriminated. They had nothing but bad things to say about their workplaces when it came to code quality, leadership, and how women were treated (both of them are female).

I know it's a sample size of two, but it makes me think that you wouldn't want to work for an employer that favors Chinese applicants as anything but a last resort.

Keep in mind that these companies are often fulfilling three things simultaneously: allowing a PRC national to gain citizenship in another country through an avenue that involves significant financial investment, laundering/protecting RMB (often the same thing in China), and, finally, functioning as what most of us consider a viable business (turning money into more money). These are listed in order of prioritization.

It's ok if the business fails completely and never turns a profit, as long as the first priority is accomplished. Accomplishing the first and second is ideal. Ending up with a viable business and a financial return on your initial investment is just a nice-to-have.
