Hi I applied for a marriage visa (Canadian to wed a UK citizen) and to stay in the UK, the wait took 12 days till i got a reply from my application (which i had to filled out first online then send via postal to the embassy - all requested documents).

They wrote

"With reference to your recent application for entry clearance. I am afraid that we are unable to resolve your application by post. if you wish to continue with this application you will need to arrrange an appointment to come into our office in person"

i have the appointment, they only asked me to bring "your passport, wich contains a valid german residence permit"

I'm very happy it's gone this far but my question is should I bring all my other paperwork just incase? and what type of questions can I likely expect to hear?
