The answer is foreign limited liability company. It is defined as an LLC which has been shaped in one state but which is now booming out business, or desires to carry out business, in an additional state. This is in direct distinction to a domestic LLC, which is a company formed in the state in which it will be doing business. The word "foreign" here just means that the main location of the business is outside the state. For example, if you have an LLC in New York and you are selling products in Indiana, you must Register as a Foreign LLC in that state.
