Oh what the heck, let's go another round...
I think we can all agree that for a long time now it has been possible to overstay the 30 day tourist entry stamp/card/visa. History suggests that the immediate risks of doing so are limited to the paying of the fine when you leave.
Announcements have been made by the Govt that it has an interest and at least a small desire in tightening immigration controls. Whether they have done so, will do so or are even capable of doing so remains to be seen. Thus far there have not been enough reports of travelers experiencing immigration problems to warrant an undue amount of consternation.
Further, I think we should be able to agree that with the updating of the immigration computer system at ports of entry (which may or may not be a completed process at any specific airport), the Govt now has the ability to monitor individual travelers and maintain a historical record of their comings and goings. It is safe to say that the Govt is in fact doing this monitoring and has been for some period of time now.
I do not believe anyone can say with absolute certainty that the immigration database will never be used to sanction travelers for overstaying beyond the limits when visiting this country. I do not think anyone can say with any certainty that the immigration practices will never change, or that those changes will not take into account a traveler's accumulated travel history retroactively which is now readily available to immigration officials when they process arriving visitors.
It may be the case that one's actions today could have some effect in the future. We can debate the likelihood of this for a long time I suspect, but no one can say with authority that anyone can safely overstay without at least acknowledging the potential for future consequences.
It is up to the individual to consider their options, and make a decision on how to best proceed in light of their individual circumstances. There is no taking back these database entries if one choose to accumulate several of them. For some, the short term gain today may or may not have an impact on future visits. Just one of the considerations one needs to think about if someone has an interest in continued unencumbered travel to the DR in the years to come. Certainly a consideration that those asking for current knowledge need to hear about so when they plan their trip they have all the info available for consideration.
