Place the softened cream cheese, mayonnaise, chili sauce, garlic powder, seasoned salt, and Worcestershire sauce in a medium mixing bowl.
Using an electric mixer, beat the mixture on high speed until smooth, creamy, and fully combined.
Scrape down the sides of the bowl as needed to ensure the cream cheese is evenly incorporated.
Add the chopped green onions, chopped fresh parsley, and finely chopped cooked shrimp to the cream cheese mixture.
Gently fold the ingredients together with a spatula until the shrimp, green onions, and parsley are evenly distributed throughout the dip.
Cover the bowl tightly with plastic wrap.
Refrigerate the dip for at least 1 hour before serving to allow the texture to firm and the flavors to blend.
Before serving, stir the dip gently if needed.
Transfer the shrimp dip to a serving bowl.
Garnish with additional chopped parsley, chopped green onion, small shrimp, and a pinch of paprika, if desired.
Serve chilled with crackers, chips, toasted bread, or fresh vegetables.
