She has got quite a few friends in both but how many do you put down i.e. is there a recommended number? For family, we're going to put immediate blood family (parents and siblings). For friends, we will put down closest school friends in Bangladesh and a couple of university friends in USA.
Basically, you should list as many family members and friends as possible/as it will let you.
So, just start with immediate family and close friends, and then keep going.
For example, for family members, you'll start with parents and siblings:
- parents and siblings
- children
- grandparents and/or grandchildren
- aunts and uncles
- first cousins
- second cousins
etc.
If she has a very large family, you might want to stop around aunts/uncles/cousins, if her family is small, you might be able to list every living relative (for example, I have a very small family... only 18 relatives in total... so I would probably list every single one of them).
We're thinking of leaving the last bit blank as my wife isn't part of any societies or anything like that.
That's fine. A lot of people won't have those things, but the question is there to cater for those who are part of close-knit cultural or societal groups that provide support to each other (perhaps in place of family).
