Hi guys. I'm in a relationship with my partner for over two years now, but we've only become defacto(Living-in together couple) for only a few months. I want to help my partner gain a work visa through partnership. He is insisting our friends must write support letters to prove our relationship, in order to satisfy immigration. I really do not want our friends to be involve or anybody else for that matter. The thing is, we both do not think we have enough evidence for our relationship, as first our evidence is limited because we are not married and we don't have children yet.
Our evidence so far include tenancy agreement, electric bill, joint bank account, photos, support letter from myself, telecom account under both our names and another contract under our names from a domestic service company. How many more evidence should we aim for?
