. You can go illegally and just stay but bare in mind if anything happend, or you are checked for whatever reason they now have a deportation system in place for you, I personally doubt they'll use it but it could cost a bit in propinas once a certain PN realises you are illegal and a new income for him. As no one can say how all this will work as it is a new system I'd probably postpone my flight, get the residency visa before you go, then complete it once there and be above board and clear minded. Wandering around the Dominican Republic with equal rights to illegal Haitians would be no fun, there is the chance it could bring nightmares for you.
