Yes, so back on topic:
The DR government does not trust its own passports, or perhaps legal residency cards as well, but now wants a dual factor authorization using a cedula.
Unless I am mistaken, that is the take away from the news article that says the government wants to more "security".
For dual DR/Other citizens I certainly see where DR the cedula can come into play if they don't hold a DR passport as in no 30 day stay on the entry stamp when entering or exit fines upon leaving after more than 30 days, but they really should do something about being able to be confident in those that do have a DR passport.
