看到UKVAS 这个信息
https://www.gov.uk/ukvcas
If you’ve given your fingerprints before
If UK Visas and Immigration (UKVI) can reuse the fingerprints you’ve already given, you’ll be emailed with instructions on how to send them an image of your face and your supporting documents.
This will mean you do not have to attend a UKVCAS service point appointment to provide biometric information.
If you cannot send the information through the instructions given, you’ll be able to book an appointment.
这是不是意味着，如果之前办签证的时候录过指纹，现在申请永居和签证有可能就不需要再录指纹了。
不过我的理解是，无论如何还是得预约UKVCAS 服务中心上传资料，所以对于要去办签证的人来说只是有可能少一个步骤，意义不大，不知道各位对这个政策有什么理解。
