Unfortunately for many Dominican applicants, Spain simply has to adhere to the rules agreed within the EU and Schengen.
1 country cannot apply its own rules.
I don't think this request makes much of an impression.
Has nothing to do with the problem at the Spanish consulate. And yes they can create their own rules of how to process the applications, that's quite obvious with how the Spanish consulate process visa applications vs other countries embassies/consulates.
My wife has applied several times and thankfully always been granted, perhaps because first time was almost 12 years ago and it's become increasingly more difficult over the years. I'm pretty sure if she would have had her first visa application today, she would most like be rejected. However, my wife's nieces who went and visited their dad in Denmark, and had to apply through the French embassy, they had no issues at all. Perhaps it has to do with the fact that Spanish consulate is using a 3rd party to process the applications whilst the French does not use any outside party to do that, perhaps because less people are applying through French vs Spanish consulate.
Anyways can testify that the Spanish embassy is sh** compared to other. And each country has the right to decide for themselves who enters and not even though it's a so called union...
