回复：谁知道现在打电话到北京美国使馆预约签证时间一般让过多久去?

if you are talking about the available visa appointment date, you can go to www.iflychina.net, click on the tab of visa appointment. you can get a reference on when is the nearest available interview date, you can search by city and visa type. Take this website with a grain of salt, not EVERY visa interviewees will contribute their appointment details to this website, but the website still provides a good reference. Hope that helps
