I am saddened by your continual lack of general and fundamental knowledge of the DR, where you are supposedly a legal resident. Since the early 2000s and then revised again in 2017, the DR has applied stricter updates to anti money laundering laws, especially aimed to combat drug trafficking and other RICO style business dealings, along with individual banking. You may be "collecting a pension" but there are many individuals and small businesses engaged in various RICO activities, especially tax evasion. The DR (esp private banking institutions) is under the gun from uncle Sam as well, as we all know, to report any significant financial positions of US persons. They [DR] clearly don't need to be on the business end of any sanctions. Stock, these are fundamental concepts and well known regulations and I continue to be saddened by your perplexity of the environment in which you live.
If we look at the record: 2009, still not that difficult to open an account. 2017 and up, much, much more difficult.
