Preheat the oven to 375°F.
To a large bowl, add cream cheese, sour cream, green chiles, garlic, lime juice, chili powder, cumin, and salt. Mix well until combined.
Fold in chicken, beans, corn, jalapenos, and 2 cups mozzarella cheese.
Add the mixture to a 10-inch oven-safe skillet. Top with the reserved ½ cup mozzarella cheese and queso fresco. Bake for 15-20 minutes, or until hot and bubbly.
Remove from the oven. Garnish with tomatoes, cilantro, and jalapeno pepper (optional).
Serve immediately with tortilla chips.
