Hey Starbug

Firstly, congratulations & thanks for sharing your experience here. You are about reach the finish line with good news that your partner will get marriage visa, what I can sense from reading your post & type of questions they have asked.
Secondly, you guys have been asked a lot of details, proofs, pictures etc which was not our case.
But at last: all end that ends well. Hopefully, you should get the good news in coming few days.

Have a nice weekend
