I have recently seen an older interview (end of 2017) with Ana Gomez arguing about the issues of the so called "golden citizenship" / "golden passports", the practice of giving visas and citizenship to foreigners who invest a certain amount of money in a country. She also urges about regulating them at the end of 2018:
The Portuguese socialist MEP took a stance against the golden visa policy in Europe this Wednesday, considering it to be “utterly immoral” to “sell citizenship” through the acquisition of golden visas.
This BBC article mentions that the EU commission has urged member countries to tighten regulations surrounding this practice:
The EU Commission has told EU states to tighten checks on non-EU nationals who acquire citizenship - so-called "golden passports" - through investments.
Clearly this is not something new and I was wondering if the EU Commission or Parliament have taken concrete steps to get tighter regulation of this issue.
Question: Have there been any concrete measures taken by the European Commission to regulate "golden passports"?
