Is it permissible to make Dua to marry a spouse from a different race or ethnicity on account of admiring their culture and finding them generally more attractive?
Bismillah,
Asalamu Alaykom,
The main things one should consider in looking for a spouse is religiosity and good manners. However there is no problem in preferring a specific type or also marrying someone if you like their culture.
Let's say for example that a woman wanted a Persian looking husband and liked Persian culture; this preference wouldn't be an issue as long as she pursued this in a halal manner.
So you may make dua for a religious spouse who fits your personal preferences.
May Allah grant you success
