We are applying for an offshore partner visa and after having read all the information multiple times, we are confident that we have compiled all the necessary documents.

I have a few things that are still unclear and was wondering if anyone could help us out:

First, we are unsure of the best way to present our documents to the immigration department. Should we use a folder, include an index, table of contents...? Which method would ensure the application was easy to understand and able to be assessed easily? I have written quite a long statement about the history of our relationship, should I attach some photos to the relevant pages of the statement, or is it best to keep all the photos together?
This may seem like a small detail and I guess it is probably the least important aspect of the application, however I can't seem to decide on the most straightforward method.
If anyone has any tips or experiences they can share, I would appreciate it greatly.

The second question is regarding photos. We have made color copies of more than 100 photos that we had stored on our computer. There are no "originals" of these photos as they are digital files. We have printed them on a4 paper with two on each page. Above the photos we have written the date and place each photo was taken and identified any other people in the photo. Do these short statements on the photos need to be notarised to prove they are true? Also, is this the best way to present photos?

I also have one more quick question regarding evidence. We have some christmas and anniversary cards that have been sent to us over the years by my mum and grandmother. We no longer have the envelopes, and they are not dated, however they are all addressed to both of us and include short letters. Could these be used as further evidence of our relationship?

If anyone can offer any tips we would really appreciate it.
Thanks!
