In fact many states require LLCs created in other states to register as a foreign entity if they do any business in that state (incl. having a presence there).

In fact many states require LLCs created in other states to register as a foreign entity if they do any business in that state (incl. having a presence there). For example in Massachusetts [0]: Pursuant to M.G.L. Chapter 156C, §48, a foreign limited liability company doing business in the Commonwealth must submit to the Corporations Division within ten days after it commences doing business in the Commonwealth, an application for registration as a foreign limited liability company ... So even if you form your LLC in Delaware, if you live/work/conduct business in Mass, then you must also register there -- it costs $500/yr and the statute requires that a non-trivial amount of information about the company be supplied including the names/addresses of "managers" for the entity as well as the registered agent. I don't know what the privacy laws for foreign entities in registered in MA are (if any), but I suspect not the same as say Delaware. If you have a footprint in more than one state, you may be required to file as a foreign entity in multiple states.
