Dulles Logistics with Overnight Layover

This summer I will be traveling through Dulles and had a logistics question with connecting flights.

On my way home my international flight is scheduled to arrive at 8pm, but I can't get a connecting flight, which will be on a different airline, to my domestic destination until 6am the next morning. So I will be stuck overnight.

After arriving and completing the customs process will I be able to stay in the airport or will I be forced to exit and re-enter through security? I hope to fly with only carry on, but am not 100% sure if that will work out yet.

I know I will have to exit to the main ticketing area and go back through security in the morning to check in for the domestic flight home, but had hoped to wait out the night at the airport vs having to add a hotel stay for just a few hours.

What airline? If you go through the main immigration area, you will exit outside of the secure area. The airport is open all night, but I am not sure that you will be permitted to go through security if you have a ticket for the next day.

United has an immigration area in the United terminal but that only applies for United passengers with United connecting flights. It sounds as though this doesn’t apply to you.

Thanks!
Will be arriving via Ethiopian Air (8pm) and leaving on Delta (6am). I was hoping to be able to stay on the "security" side of the airport, not have to exit and re-enter since I don't think I would be able to reenter the night before my flight leaves.
