DOMINICAN REPUBLIC ENTRY REQUIREMENTS:
As of April 2018, the cost of the tourist card while visiting the Dominican Republic will be included in airline tickets.
With the new inclusion, visitors of the Dominican Republic will no longer need to purchase a tourist card separately.
If staying beyond 30 days, visitors can expect to pay an additional fee upon departure–determined on a sliding scale according to the total length of your stay. Those fees can be be paid at the airport’s immigration section–after check-in and past security–upon departure.
There is also a US $20 departure tax required by law, which is always included in your airfare.
