Readability between sans serif and serif for "foreign language users"?

I am curious about whether "foreign language users" find a difference in readability of text between sans serif and serif.

Here, I am defining "foreign language users" as people whose primary/first language following a "non-Latin script" writing system (for example, Chinese, Arabic, Devanagari, Cyrillic, etc.).

If Latin script is not the primary mode of writing for a person, is there a preference for serif vs. sans serif (in Latin script)?

I would intuitively guess that sans serif is more preferable, but I am curious what research says about this.
