詳情這裏：老爸申請B2，要求補充材料，為什麽？急！！！

我老爸申請B2，為什麽叫他填DS－158。還要叫他回答以下的問題：
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

是不是簽證官把他當成了訪問學者了？
有沒有人有類似的經曆？請回答。我在線上。多謝。
