It seems the people who do have residency want others to experience the same pain they have went through in getting settled here. But most won't bother. Snowbirds aren't tied to DR (with house, car, spouse, kids etc) it's just a long vacation.
So if all else fails snowbirds will just change the airport code when they buy their ticket and find a new place to spend their winters.
It might not be fair to say "the people who have residency". I'm am sure residents have feelings on this issue that differ from one to the other. In my case, yeah, I kind of do want people who wish to live in the DR for a time period beyond what most would consider a normal tourist stay to play by the established rules (whatever those may be) like the residents have done.
Part of this immigration acrimony comes from some sort of feeling on the part of a few that they are special and the rules don't apply to them. Some take much delight is promoting a work around that they clearly know by now is not legal and not condoned. DGM itself has described the exit costs as "fines" not fees. Prominent lawyer(s) have said that the fines and the practice of overstaying is "extrajudicial".
Yet for some, it seems to be a high hurdle to clear when it comes to accepting that what they have been permitted to do in the past may not be permitted quite so openly in the future. Those who do follow the rules which involves ongoing expenses in time, effort and money can understandably feel a bit perturbed by those who choose to circumvent the system for personal advantage.
We already know that snowbirds are not really a significant economic factor in this country as a whole - acknowledging that some here make their living catering to these people almost exclusively. We already know that the numbers of snowbirds that do come here is small(ish) on a yearly basis and those numbers do not seem to be trending upwards.
It would be appreciated, at least by me, if those who continue to threaten to take their ball and go elsewhere, would stop whining about it and follow through. It's not up to "us" to make the DR alluring for retirees and even less so for retirees and people with a predisposition to conduct their affairs in an extrajudicial manner.
If your neighbors had to put a fence around their pools to the tune of $5000 each and for some reason you do not, of course those neighbors are going to be upset and grumble about your ability to skirt the rules. That's only understandable. Once people accept they are not special and more important than everyone else, perhaps some of the animosity will diminish. After all, the most successful criminals are the ones who can keep their mouths shut and not brag about or openly promote their exploits.
Those who take affront at the annoyance of others with respect to this overstay practice clearly have not though hard enough about what they do and either haven't yet or are unable to see beyond their own selfish interests - which is pretty common these days and perhaps a big part of why our societies are so ideologically polarized between those who can only see "me" and those who choose to see "us".
