It's been a long time since I applied for any visa (since received an Oz passport basically), so fell behind in my knowledge and skills. Now my wife needs Swiss visa and she keeps mentioning VFS, which I'd never heard of until today.
Question: is it a requirement to apply via VFS or one can simply show up at the embassy? Does it take much longer to apply w/o VFS's assistance? I see lots of negative feedback about them, and from their website I cannot grasp nature and usefulness of their services, considering that for a Schengen visa everyone has to show up in person anyway (for biometrics).
