Answer : There is no one-size-fits-all answer to this question, as licensing requirements can vary from state to state. However, in general, interior designers may need to be licensed in order to use the title "interior designer" and/or offer their services to the public.
Some states require that interior designers complete an accredited degree program in interior design, while others may only require that they pass an examination. In some cases, interior designers may also need to complete a certain number of years of experience working in the field before they are eligible for licensure.
