In its natural range in the Americas, raccoons are natives and not an introduced or invasive species. As a result of escapes and deliberate introductions in the mid-20th century, raccoons are now also distributed across mainland Europe, Caucasia, and Japan where they might be considered as invasive.

"Invasive Species" is a term used to describe a species that is taken from it's natural environment and introduced somewhere else. The species then cause harm to the new environment it was introduced in.
Invasive species
No, not all introduced species are invasive because they may have a natural predator that will eat them in their new environment. Also because the species can be biologically controlled, chemically controlled or mechanically controlled.
exotic species
The Nile Perch is one of the Invasive species located in Lake Victoria, Africa. It was introduced as a sporting fish, but it soon became one of the 100 Worst Invasive Species by the IUCN's (International Union for Conservation of Nature) Invasive Species Specialist Group. Other invasive species include the Nile Tilapia and the Water Hyacinth, which is a water-type weed.
A species is not inherently native or invasive. All species on Earth have a region to which they are native. If they are introduced to a new area, then they are invasive to that area. The orca has a cosmopolitan distribution, so it is native to oceans pretty much everywhere.
introduced to a new area, spreads rapidly, and displaces native species
The introduced fish species would not become an invasive species if the fish shares a niche with the native species.
