Hey guys so I'm just posting this to share my experience.
I'll explain my situation-
I met my NZ boyfriend in September 2014. I had to move out of my apartment in Dec so that's when I moved into my boyfriend's parents house.
In January we started to collect evidence. I kept anything with my name and address.
I submitted my visa with the following evidence-
* Bank statements/Online order receipts
*I wrote a letter outlining our relationship/ My partner wrote a letter and so did both his parents also outlining the relationship and that I have been living their since December.
* Emails we sent to each other whilst at work
* Just over 500 pages of Facebook conversations. I also sent a copy of Facebook messages with other people when I've been discussing anything to do with our relationship.
*Confirmations from weekends away/days out
* Pictures of us both and both of us with each others family.
* Facebook status's
I also made sure I was organized with the paperwork. I categorized all the conversations into date order and labeled everything to make it easier to read.
After getting all the information gathered. I applied for the visa on 02nd May and it got approved today so I feel very lucky to have it approved so quickly. Any one else going through the process I would just advise to get as much information as you can even if you think it's irrelevant it might help your case.
Good luck to everyone else out there
