After a year the overbite should be gone and if not it might just take a little bit more time.
Just make sure you're wearing the Invisalign as often as you should and then after a year you should see great results.
Results don't happen overnight but you should see results pretty soon.
Just make sure you do follow up appointments with your dentist if and when required.
