Nope they can't. I ended up regretting it though lol moved in with some friends when I turned 18 and it turned out bad. Move back in with parents til I turned 22 and had a stable job to get my own apartment

Nope.

Nope but if your phone is on their plan or if your car is under their name they can keep them

the only thing they can do is make u pay for school yourself if they are paying for it. otherwise u are 18 and are free to go
