回複：Wife cannot get H4 visa

My wife's H4 visa got rejected twice. My coworker introduce her to me and we dated for a year(send emails and call each other every day). Last fall, I went back to China and married. When seh applied for H4 visa, she got rejected because the VO didn't believe our marraige is true. This Feb, I went back and we applied together, My H1 is approved and her H4 was rejected. What can I do?
