详情这里：老爸申请B2，要求补充材料，为什么？急！！！

我老爸申请B2，为什么叫他填DS－158。还要叫他回答以下的问题：
1. Detailed resume or curriculum vitae (CV), including a liat of all publications
2. Detailed description of your inviter’s business or your advisor’s research in the United States, including his/her address and telephone number
3. List of people in the United States who know you well ,including their addresses and telephone numbers
4. Detailed description of your company’s products or services in China (former employes)
5. Complete itinerary in the United States, including all meeting, conferences, and visits,and the names,addresses and telephone numbers of your hosts

是不是签证官把他当成了访问学者了？
有没有人有类似的经历？请回答。我在线上。多谢。
