Foreign qualification
Foreign qualification is the process of registering a company to do business in a US state other than the one where it was formed. 'Foreign' here means out-of-state, not international. It is required once a company has sufficient physical presence or activity in another state.
In plain terms: Registering your company in a second state because you actually operate there.
Why it matters
This is what defeats the popular idea of forming in a low-tax state while operating elsewhere. A Wyoming LLC run from California must generally qualify in California and pay California's fees, which means two sets of obligations rather than none.
Common misunderstanding
Believing the formation state determines where you owe. Activity determines it.
