Preheat oven to 350 degrees F.
To make the marinade, combine the orange juice, lime juice, minced garlic, oregano, Sazon goya, cumin, salt, and pepper.
Remove the pork skin 3/4s of the way and make several 1-inch cuts into the pork.
Pour the marinade all over the pork except for the skin. The pork skin should remain completely dry. Make sure those garlic chunks get inside the slits.
Place the skin back in place, pat dry the skin with a paper towel, you want it to be extra dry. Season it with salt and pepper, cover it with aluminum foil, and bake for 4 hours. Once the four hours are up, uncover and bake for 1 hour. After the 1 hour, increase the temperature to 450 degrees F. and cook for 15-20 minutes or until the skin is nice and crispy.
Once the skin is crispy, remove it from the oven and let it sit for 10-15 minutes. Slice off the skin and set it aside. Shred the meat and place it in the pan with the juices. Make sure not to get the juices on the pork skin otherwise, it will soften. Serve and enjoy!
