In the bottom of your slow cooker, add the chicken, beans, corn, green chiles, onion, and garlic. Stir gently to combine.
Pour in the chicken broth, then add the cumin, oregano, chili powder, and cayenne pepper. Stir to mix well.
Cover the slow cooker and set it to cook on LOW for 6 to 8 hours or HIGH for 3 to 4 hours.
Once cooked, shred the chicken and return it to the slow cooker.
Stir in the cream cheese, half and half, and cilantro. Cover and cook for an additional 15 minutes on HIGH.
Season to taste with salt and pepper. Serve hot with toppings.
