I submitted mine (Spouse visa) last Tuesday, it took only 20 mins.
If she arrived earlier to her appointment time, tell her to go straight in VFS office to get her a number to be called, together with a form to fill up,it's for SMS and email service, she need to put her mobile number and email address, then signature at the back.

The checklist form should be follow on how to organize the papers so it's easy for them to check it.

after that she will be receiving receipt and a purple tagI think that's the bar code of the docs,then wait her name to be called for biometrics that takes few minutes

btw there's additional charges for SMS 110 pesos and courier fee 330 coz I want it deliver here in my town

Goodluck to your wife Mistermatty
