Visa for ParentsSorry, no Chinese input in the office. I have a few questions for visa for parents.1.I am American citizen for over 10 years, parents never come to USA. Will they need to go to BEIJING for visa? 2.If they are over 65 years old and have medical conditions, can ZHONGXIN apply visa for them? I heard ZHONGXIN can handle visa for people.3. During the wAIting period of immigrant visa for the siblings, can sibling come to USA for a visit?
