Hi, I am Japanese and my sponsor British. I am going to apply spouse visa in 3 days and I have preparing suporting documents.
There are 9 cotegories
(Appendix2, Employment evidence, Financial evidence, Educational evidence, Sponsor evidence, Consent letterd and Proof of relationship, Accommodation, TB certificate, Additional documents)
I am not sure which cotegory I have to put

1, Sponsor'e letter of natiotal insurance number
2, Sponsor's letter of Group personal pension.

I prepared these because of there is his current address on the letter. It would better to show these to Home office that he has really living on this address.I thought it might be in Additional documents.
However, these are can be in Sponsor evidence…

Does anyone know which cotegory I have to put this 2 documents???

Thank you.
