A children's psychiatrist from Berkshire says he is being forced to leave the country, because Home Office officials will not allow his Indian-born mother to stay.
Dr Warikoo, was born in India, but became a British citizen in 2014. His wife and 13-year-old daughter are also UK citizens.
He's worked in the NHS for 15 years, and says if his family can't stay together he will quit his job and move to Australia.
For the past four years he has made numerous representations to the Home Office to allow his 71-year-old mother to remain in Britain, but he still hasn't had an answer, so has reluctantly taken the decision to apply for work in Australia.
Nishchrint Warikoo currently works throughout Hampshire and Sussex for the NHS as well as looking after his mother Phoola.
The Home Office says it is reviewing his case and they will be in contact in due course.
