In a large bowl, combine the masa harina and warm chicken broth. Knead the masa until it forms a soft dough.
In a large skillet over medium heat, heat the olive oil and add the onion, garlic, and jalapeno. Cook for 3-4 minutes until the vegetables are tender.
Add the shredded chicken, cumin, oregano, and sea salt. Cook for an additional 5 minutes until the chicken is heated through.
Add the salsa verde and cilantro and cook for an additional 1-2 minutes. Remove from heat and set aside.
Soak the corn husks in warm water for at least 10 minutes to soften them.
Lay a corn husk on a flat surface. Spread 2 tablespoons of the masa dough on the husk, leaving a 1-inch border on all sides. Add 2 tablespoons of the chicken mixture in the center. Fold in the sides of the husks and roll to form a tamale.
Repeat with the remaining husks and filling.
Fill a large pot with 1 inch of water and place a steamer basket in the pot. Place the tamales in the basket, cover, and steam for 25-30 minutes.
Serve the tamales warm with additional salsa verde.
