To register Foreign Entity one needs to file an application with the concerned authorities and pay a fee. In most states, registration requires disclosure of the company name, state of incorporation/organization and the name and address of the registered agent in the state for which the application is being made.
Keeping The Registered Name
A Foreign Entity can be formed with the original registered name, provided that this name is available in the state where the Foreign Entity is planned to be registered. Otherwise, the company will have to adopt a name that does not conflict with any other company name or a trade name (DBA).
