申请美国签证时，并不是所有申请都能当当场知道签证申请结果的，美国签证申请有一种情况叫做行政审核，签证申请如果被行政审核或是需要等待补充材料额话，就不能立即知道自己的美国签证申请结果，签证申请人在申请美国签证后，可以通过美国签证查询进度电子系统查询签证状态：

在网站内输入申请的签证类型、面试地点和护照号码即可查询。通常有如下显示：

提交DS-160申请表后：

No Status

If you have submitted your online nonimmigrant visa application (DS-160), it has not yet been processed into the visa system. At some locations, your application will remain in this status until you appear for an interview or until your application is ready for review. Please see the embassy or consulate’s website for information on the next steps required for visa processing.

面谈前：

Ready

Your case is open and ready for your interview, fingerprints, and required documents. If you have already had your interview, please check your status after two business days. If no interview was required, please check back in two business days for the status of your application.

面谈通过后一段时间内或行政审核：

Administrative Processing

Your visa case is currently undergoing necessary administrative processing. This processing can take several weeks. Please follow any instructions provided by the Consular Officer at the time of your interview. If further information is needed, you will be contacted. If your visa application is approved, it will be processed and mailed/available within two business days.

若签证被签发：

Issued

Your visa is in final processing. If you have not received it in more than 10 working days, please see the webpage for contact information of the embassy or consulate where you submitted your application.

若签证被拒绝：

Refused

The case has been refused for a reason other than those listed in Administrative Processing.

美国签证行政审查结果只有两种——签发与拒绝，查询结果即可知道，美国签证查询进度电子系统更新可能存在延迟，所以申请者不要急于查询。
