As such, shareholders must file an Articles of Incorporation with the State of Illinois to receive their corporate status.
Foreign corporations are no exception.
A foreign corporation is any corporation not incorporated by the State of Illinois. That would include corporations organized under the laws of the various other States in the United States of America or of other countries. Corporations formed under the laws of other States or Countries cannot do or transact business within the State of Illinois until they register with the Secretary of State. Although a foreign corporation may be valid in the State of incorporation, it is not recognized as an official corporate entity in the State of Illinois until it receives a Certificate of Authority from the State. In addition, entities transacting or doing business within theState of Illinois without a Certificate of Authority may be subject to penalties and, even worse, may not receive the benefits of limited liability or other corporate attributes which come with a valid corporate entity.
