So, I can only assume that they will pull the same crap that they pulled on my residence card. I was charged 2000 DP in fines for being late, even though I was told by them I had the extra time. Stupid stupid me for falling for it twice. Live and learn is a daily occurance here, like going to idiot school.
Are you saying Migracion, the department for residencia, told you you could have the extra time, with no penalties? That's very odd. Paying a fee for late renewal of residencia is established practice & the amount is on their website (RD$500 for each month that your provisional has expired, RD$250 for each month that your permanent has expired).
Direccion General de Migracion
Now I know that sometimes when it is a large sum, they exercise some discretion (happened to a friend of mine who was nearly 2 years late in renewing her permanent residencia) but they do charge for late renewals & have done so for many years.
The JCE for cedulas is different, however. Up until recently cedulas were free (in fact the only time I have ever paid a fee for a cedula renewal was when I last renewed, which I think was December 2008). So the applicant was not gaining a 'free period' by renewing late. That's why it is easy to believe that the JCE told you you could renew up to 6 months after the date on the card. But for Migracion to say this ALSO is really surprising and probably should have been challenged.
Course it is always possible that at some stage in the future the JCE might impose penalties for late renewal of cedulas...goalposts do move here in the DR, as you have found out.
