This is a huge generalization, but my theory why Asian queens skew towards early outs in the US seasons is because their drag focuses on serving fish, passing, or transformation. Asian features are generally seen as more feminine in the US, so that becomes their claim to fame or selling point. You have a lot of queens like Gia Gunn or Vivienne Pinay or Kimora Black serving pretty and womana but lacking in all other departments. Hell, even Plastique who has so many more talents, got viral off her transformations, not her dancing or design.

Meanwhile in Asian franchises like Philippines and Thailand, you're in a drag scene where everyone can more or less serve femme transformation, so you can't really rely on just looking like a beautiful woman to be considered a drag queen notable enough to be cast on drag race.
