My parents are a bit similar about it,if I want to date someone,they should meet him/her and have a talk together.They’re pretty open minded about it,the ethnicity and religion is not a criteria,and I.m allowed to date men and women.But they take extra care that he/she respect me,treat me well,not do any dangerous activity(using drugs,being alcoholic,spending time in bad company...);being smart and well educated is important too.Of course,they should wear normal clothing(no ripped jeans or similar),not using vulgar language,etc...
I guess it is similar to Sara2001’s parents requirements.
P.S.:In my case,if my parents approve a boyfriend/girlfriend,it means he/she will probably be approved to marry me later,if he/she propose me,too.
