收到P3包裹后，会要求去在线填写DS-160表格。此表格很重要，里面信息一定要仔细，不要填写错误。英文不好的可以直接百度“如何填写DS160表格”，百度经验里面有一步一步的解释说明。填写过程中时刻记得保存。
Visa Status Check
https://ceac.state.gov/CEACStatTracker/Status.aspx
（1）如申请非移民签证，输入面谈地点和DS-160表格条形码编号（申请识别号码），在线查询DS-160表格及签证申请状态。选择：NONIMMIGRANT VISA(NIV)，在“Select a location”里选择你申请签证的地点，然后在下面的文本框（Application ID or Case Number）里填入DS-160表格条形码编号即可以查询到您的美国签证状态查询（K1属于非移民签证）
（2）如果申请的是移民签证，则可输入档案编号。
几种状态中英文说明如下：- 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.
提交了DS160，还没有安排预约面谈。
- 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.』
你已经完成预约面谈，请在两个工作日后查询。
- 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.
你的签证正在审核。如果政审，只有等了哦。
- 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.
签发签证。如果10个工作日还没有收到签证，请直接联系递交签证的大使馆或者领事馆。
- Refused:
The case has been refused for a reason other than those listed in Administrative Processing.
因政审中的某条签证被拒。。
如果状态为issue，说明没有问题了，已经签发了，则直接去签证预约的网址，各个国家不同，在预约网站查询护照状态；如果状态为AP，则说明正在材料审查，需要更长的时间等待。

里面可以看见各种签证的Current Processing Times
当时我申请的时候，我老公用这个网址查询签证预计需要多久。我几乎没怎么查看过，每天该上班就上班，该干嘛就干嘛。
其实没必要天天去查询，美国签证的时间现在越来越长。原来K1签证半年差不多可以拿到，现在需要更久的时间了。所以，最好等你觉得差不多了再去查询，不然天天看着状态没变化也蛮烦的。签证填写表格和准备材料，最重要的是细心和耐心，建议填写完了再检查一下。
如果有更好的美国签证查询网址，欢迎补充。
