Permanent...once the metal has oxidised -there is no way to reverse it.
Yes, metal rusting is a chemical change in matter. It involves the metal reacting with oxygen in the presence of moisture to form a new compound (rust), which changes the chemical composition of the metal.
The rusting of a metal chair is a chemical change. The iron is undergoing oxidation as it combines with oxygen to form iron oxide.
Rusting is a chemical change because it involves a chemical reaction between iron, oxygen, and water to form iron oxide (rust). It results in the formation of a new substance with different chemical properties than the original iron.
Rust (oxidation of metal) is a chemical change but it is also a physical change in the strength of the material.

Metal rusting (corrosion) is a chemical change.
Rusting is the oxidation of a metal and is an example of a chemical change.
It depends on what metal is 'rusting'.
If by non rusting you mean it is in the same state it was made in then it wouldn't be part of any change. But if something is rusting it would be a chemical change because the metal is changing composition and it is not the same metal it was in the first place.
Rusting is a chemical change because the metal is reacting with air and changing into a new substance.

a chemical change.
Is an example of chemical change, reacting to air
I don't think it is. It's a chemical change.
A nail rusting is a chemical change. The chemical formula of the metal completely changes, adding oxygen to the formula. Iron changes from Fe to FeO2 , or to Fe2O3
