Many foreigners like to marry Koreans. I don't know if there's a connection with the famous Korean dramas or it's just because of Korean Dream. There are even agencies who are looking for korean guys who want to marry ladies from the Philippines, Vietnam, China, Cambodia, Laos and Thailand. They just match their pictures and get married without knowing each other. That's one of the main reason why most of them can't live well.
Sad to say that ladies from these countries want to get married to Korean because they want to escape from their poor country. They think if they marry Korean, they can help their families back home and can live well. Is that really what happen to women who got married to Korean? A few, I think! Those who are lucky.
What I've noticed is that koreans who get married to these foreigners who are using Matching Agencies are those who couldn't get married to Korean girls. Because most of them are old, not good-looking, or farmers. Most Korean ladies like men who have either good jobs, handsome, or rich.
I can say that Korean guys are sweet, responsible, and kind. But don't expect too much. Remember that communication is always a barrier. Not to mention the culture and mother in law.
By the way, most foreigners who got married to Korean guys because of love live well. Those are the international couples who got married through courting. Although there are some who got divorced because they had trouble with communication and Korean Cultures.
