It's called Tree Of Heaven.  They are indeed considered an invasive species to the US, and they are damn near impossible to kill because the roots shoot out underground runners, while the trees themselves drop seeds everywhere.  Back when she and I were smokers, we had a flower pot on the porch that we used as an ashtray.  Somehow a seed got in there and it sprouted.  Despite putting cigarette out on it, repeatedly, every evening and regularly setting it on fire, and any water getting into the soil of the pot passing through a pound of cigarette butts, I never could get the thing to die...

One lot over from ours, the residents have a 30+ foot one in the back of the lot, so there is no way I will ever be rid of those damn things.

The very one and only.. It was introduced in the US as a "valuable shade tree".. I guess value is in the eye of the beholder.. 
To be fair there are more than plenty of worse invasive species of plants, kudzu in the south is unbelievable in certain areas. Another around here is confederate jasmine, but people usually like it because it's so wonderfully fragrant, but it can absolutely take over an area. Our backyard smells great for about 2 weeks every spring. The rest of the year the stuff is a PIA.
If you like mulberry wine you have plenty of those suckers all over Ohio and everywhere else up north.
Although it's seldom harvested it's one of the great woods to work with especially for musical instruments..
If you want real problems with invasive species with root problems check out the bamboo forests that pop up especially here in the south. The species here are generally useless except for maybe making fishing poles..
