In a large mixing bowl, blend together the softened cream cheese, sour cream and mayonnaise until smooth.
Stir in 2 tablespoons of the sweet chili sauce, soy sauce, lump crab meat, ¾ cup colby jack cheese, garlic, brown sugar, sriracha, salt, pepper, and ¼ cup green onions into the cream cheese mixture until well combined. Adjust salt and pepper to taste.
Spread the mixture evenly into the bottom of your prepared baking dish.
Sprinkle the remaining shredded colby jack cheese over the top of the dip.
Place the dish into the oven and bake for 25-30 minutes until the cheese is melted through and bubbly. (Optional* put the dip under the broiler for 2-3 minutes to bring out a light golden brown color in the cheese).
Pour the remaining ¼ cup of sweet chili sauce over the top of the hot dip and spread evenly. Garnish with leftover sliced green onions.
Serve immediately (dip will be hot!) with tortilla chips, crackers,sliced bread or fried wontons.
