That's the case of most Haitians living in the DR, even the ones that went through the regularization plan from a few years ago. The main problem was that to keep their regularized status, they needed to renew and the vast majority didn't. Not renewing meant returning to illegality. I assume that the Haitians that regularized during the regularization plan kept their papers that implies they are legal in the country even though most of those papers are now void due to not renewing.
The same yearly renewance is applied to the Venezuelans that regularized in later years as the government put a regulrization plan just for them. It will be interesting to see how many of the regularized Venezuelans renew and doesn't relegade to illegal status.
The declaration about how most Haitians that regularized during the regularization plan became illegal again by not renewing is said multiple times in multiple interviews by the former Director of Migración, Enríque García. Here is one of those, this one from July 29, 2021. Unfortunately for most DR1ers since they don't know Spanish except a few words such as "una cerveza por favor" (and many not even that), this is in Spanish only and the subtitles can be activated, but from what I can tell they too are available in Spanish only.

If this is the case, that almost all Haitians in the DR are illegal for not renewing the papers they received during the regularization plan, DR1ers are implying that Migración and other authorities when presented these papers by Haitians, to pretend those papers are legal even though they are seeing the papers are expired and void?
By the way, until very recently even Dominican birth certificates had expiration dates and that was for everybody. Having an expired birth certificate was like having nothing since anyone in the government was authorized to accept the non-expired ones which was given upon asking for them at the corresponding government entity.
