How come american people always judge and say that asian girls use you for green cards?

[John]

People always think that foreign brides from asian countries uses american men for green cards. I'm a young vietnamese guy in my early 20s and my fiancee is about 1 year younger than me. People still think she will use me for a green card. It makes sense if i was about 30 to 40 years older than her but I'm only a year older. Sure I might have a hunchback and look different from other vietnamese guys in San Jose but my marriage to be has more potential to work out. How come american people always assume this ?? You think that when you american women are nothing but a bunch of greedy clubbing money hogging freaks. Vietnamese girls from vietnam are not like that. My fiancee loves me for who I am. Why do you still think she is using me for a green card when she clearly said she likes me. I mean she agreed to marry me when my relatives in vietnam asked her.
