Hi everyone. So my step dad has been around for 27 years as my dad. but never married my mum. They lived together in a joint mortgage for 20 years and have recently decided to live apart but are still together . I desperately want to see them both. My question is ! How do I prove he is my Step Dad ? He has been here many times. I am a permanent resident. I am currently getting citizenship but it's help up due to covid. ?
