My parents were rejected visa because I stay in the U.S. for 7 years and never come back China once, and married in the U.S. The visa officer said my parents have immigration trend and rejected their visa. My first baby will due on Oct. this year so I need my parents to help me with it. My parents will go to the Beijing visa office again on late Sep. If anyone knows how to pass this situation, please help me! Thanks in advance!!
