Invisalign on lower teeth for crowding.

My second bicuspid has always been crooked & it comes under my tongue. It wasn't a problem even though my lateral incisors were pushed back. I think it'll have to be removed & I think I will need surgery for my wisdom tooth. Can I get Invisalign on just the lower part? & if not then is it possible to get them on the upper half for a lesser period of time only when needed? Can both my extractions be done with General anaesthesia because I have severe anxiety.
