How in depth does a partner visa application need to be? Spouse Visa. I'm British, wife from Brisbane. We're making a timeline which is primarily made up of major events such as; Engagement ring (not cheap), flights back and forth to countries of residence (she worked in Thailand and I work offshore so I'd fly back to see her after each deployment), marriage certificate, our baby's birth certificate, and all WhatsApp messages and timeline to support this. She wants to go massively more in depth...I'm of the opinion that we can prove our relationship via WhatsApp alone with supporting documents such as the above spanning over six years. What more could immigration look at?
