There isn’t a reliable public count for “how many Taiwanese moved to Arizona for TSMC.” What’s documented is that TSMC’s Arizona buildout has brought an influx of skilled workers from Taiwan, but reports don’t give a single verified total.

What the reports say

  • Coverage describes Taiwanese engineers and families relocating to support TSMC’s Arizona operations, especially around Phoenix.
  • TSMC’s Arizona expansion has continued to grow, with major new investment approved in 2026.
  • Public reporting focuses more on the workforce and community impact than on a precise headcount of Taiwanese arrivals.

Best estimate

If you want a number, the honest answer is that no authoritative public figure is available from the sources I found.

  • The number is likely in the hundreds to low thousands across multiple waves of transfers and family moves, but that would be an inference, not a confirmed count.

Why it’s hard to pin down

  • Companies usually don’t publish nationality-by-location relocation totals.
  • Some workers are temporary assignees, while others settle longer term.
  • A lot of the visible Taiwan-linked community in Arizona includes both direct TSMC staff and broader semiconductor ecosystem workers, not just one company.

Quick takeaway

So the most accurate answer is: TSMC’s Arizona expansion has drawn a noticeable Taiwanese workforce, but the exact number moved there is not publicly confirmed.
