Indeed. I lived in south korea -- around 2018 I started seeing a lot more low-status filipina immigrants/foreign workers appearing in the "foreigner" parts of town.

They were clearly hunting for white men, but the education/culture gap was too much. These women mostly didn't even finish high school.

But when my future wife came along (PhD student with ambition and plans to move to USA with or without me) and that was a completely different story.

It is just an anecdote and not even one directly from PHI, but it does conform to what you said.
