What is Foreign Entity or foreign entity qualification?
A foreign business entity is an entity formed under a statute or common law in a jurisdiction other than the state in which your corporation was originally formed. The foreign LLC or foreign corporation is registered with the state where you want to do business. It is also known as Out-of-state entity.
For Example: If your company is incorporated in the state of California, but now you want to expand your business in the state of New York, then you would have to file as a foreign entity within the state of New York. In other words - you must apply for authority to conduct business in New York.
