查了一下 移民部网站的更新 :
If the site closest to you is closed, we’ll automatically extend your deadline to give your biometrics.
You don’t have to give your biometrics until the sites reopen. This applies to you, even if your biometrics instruction letter (BIL) says you have 30 or 90 days.
You don’t have to contact us for this extension, and you don’t need a new BIL to make another appointment when sites reopen. Bring your original BIL to your new appointment to show proof of payment.
Your application won’t be refused or closed if you can’t give your biometrics due to COVID-19 closures
应该是 如果签证中心继续关闭 咱们的申请可以自动延期 直到那边重新恢复开放 现在也只能等了
