Do I have to ask for permission to visit the statue? or schedule on which site

I think you have to get a authorization if you want to get in the Statue of the Liberty but if you are going to visit only you don't need to get any authorization.

Hello there are several possibilities you can visit the island without entering the statue or pass to see just the base or the complete visit and you can climb to the crown here is a good visit

I'm sorry I can only read English.
