All the businesses in the USA registered in one state are required to obtain a Foreign Qualification certificate to operate in another state. This rule applies to all corporations. The term “foreign” appears to be something international. However, this is not true; you need Foreign Qualification if you are thinking of branching out your business to other than the original place of incorporation in the USA [the state where you registered your company and the state where you want to expand your operations.] The concept of Foreign Qualification services in the USA applies to all entities such as Corporations, LLCs (Limited Liability Companies), LLPs (Limited Liability Partnerships), and LPs (Limited Partnerships).
