There is insufficient information available to create a comprehensive Wikipedia-style article about Open Door-USA Inc (EIN: 821845003) as it appears to be a separate entity and not directly associated with the well-known Open Doors organization that supports persecuted Christians worldwide. The search results primarily detail Open Doors International USA, Inc., which focuses on supporting persecuted Christians globally, and another unrelated organization called Open Doors Organization that aids businesses in the disability market. Without specific details about Open Door-USA Inc's mission, history, or activities, we cannot generate an article. If you have more specific information or context, it might be possible to assist further.
