Yes please can you give me the answer especially as a Muslim Female, I am very curious.I have Canadian passport but I live in U.A.E..if that gives more information..so can you guys give me an answer 
Absolutely. I’m sorry if you ever got the impression that Koreans only accept white people into the country or anything, but there is no discrimination against student’s ethnicities in Korea. I mean, yes, korea does have problems with some illegal South Asian immigration, so it might be a bit harsher on the immigration side, but since you’re just coming over to study as a student there is no problem.
If what you are worried about the religion part of it, you shouldn’t need to worry about that either. Korea’s not intense like America about muslims and although most of Korea is Christian, there are also several renowned muslim temples throughout the area if you look for it. No, people will not care what religion you are. I mean, people of foreign ethnicities aren’t that prevalent in Korea so they may be a little curious about you when you are there, but trust me, it’s nothing hostile. Most Koreans are enthusiastic about foreign students coming over to study in Korea and they react the same way to eveyone no matter what your ethnicity is, if that’s what you’re concerned about.
As for a homestay program, they arent that common in Korea as they are in the US or Canada. Just the concept of "homestay" itself is not that common in Korea (yes, korean students do it a lot when they go over to other countries, but koreans living in korea don’t tend to host often). If you have already found a homestay program in korea, then great! ;] If you haven’t, just keep that in mind that it may be a little difficult.
Hope I helped!
