Fact: the US is not losing undocumented / illegal immigrants at an abnormally high rate. That's a myth. Trump has hardly moved the needle at all when it comes to illegal immigration. Everything to the contrary is propaganda pushed by the media for pathetic political points / ratings.
Obama deported more people in an average year than Trump has in his first year. He was known in immigration circles as the deporter in chief for it.
Those are relevant facts but they leave out immigrants who are leaving voluntarily. I couldn't find anything within the last 6 months but there was recently a net outflow of undocumented immigrants [0]
