I was just wondering who here has recently applied for the affirmation of freedom to marry from the British embassy?

I'm going to have to do it soon and I just had a few questions.

I've had a browse on the .gov website and even went a few steps into the application by but didn't get far as I do not need to apply yet

How much does a marriage and visa cost? How long does it take?

I found a girl I love very much and want to spend the rest of my life with her, forever.

Currently, I am on the Covid visa, can I convert that to a marriage visa? What is require for marriage visa? Letter from Embassy? pound of flesh? What does it take to get married?

Anybody with recent experience?
