I'm just speaking from my experience with my brother and a wannabe American citizen (he was the only one in the family who couldn't see that she didn't love him and was using him). She'd stay for three months, then go back to Germany, stay three months, then go back to Germany. Customs got so suspicious that they thought she was a drug smuggler and held her for a day. My brother got her a brief fiance visa, but thank God he realized that his family and friends hated her for a reaon. (She was six feet, 10 inches tall, and had close to model looks). But she talked to my brother as if he was a slave one time, and we almost had a catfight. She told me, "I'm going to get you out of Andy's life." And I said, "Not before I see your ass go back to Germany with no engagement ring." My brother made good money, and last that he knew (he's now married to someone different), she was dating a rich Asian guy.
