This question already has an answer here:
I'm looking for an early 90s TV series in which aliens set up embassies on Earth. They were human-like, with a pale blue skin.
Their ships were alive and grown rather than built.
The story focused on their ambassador in the US and its relationship with a human (cop?) who discovered little by little they were not the benefactors they appeared to be.
Oh, and they used nice smartphones with retractable screens.
Well, I can't tell much more about it...
