Answer to this question is dead simple. In America,how many of you have seen an old interracial couples who grew old as husband and wife after 20-30 years of marriage.In this case lets say American born wife of a Nepali born husband (who first came to the US as a college freshman). Satistics tell something ? Another important aspect is how much are you willing to assimilate into the culture of your American born girlfirend inorder to get married to her and how is she willing to assimilate into our culture ?
