The LLC have been a traditional form of business structure in Europe. In Germany for example, the LLC is the equivalent to a "GmbH". The LLCs made their way to the United States in the late 70s, with Wyoming being the first state to introduce legisation, as of today they are accepted as form of business in every state. LLCs are very popular since they combine advantages of a partnership with those of a corporation.
There is no restriction on doing business with US residents, however if the LLC is foreign or non resident owned tax will be liable on profits generated within the USA.
The company may not use a name identical or similar to an existing company so as to cause confusion. The name must end: LLC, L.L.C., or Limited Liability Company
