Finding a foreign husband gives a woman a chance to leave her country and find better economic opportunities. Marriage is a substantial part of Russian culture, with 30 years being the age at which a woman is considered an "old maid". With 4,138,273 more women than men from the ages of 15 to 64, marriage opportunities are slim at home and worsened by the life expectancy difference between men (64.3 years) and women (73.17 years), as well as the fact that a large portion of successful males are emigrating out of Russia.
