It’s not a scam. It’s probably not the best bank around. But I bank with them since 2015 and never had big problems with them. They offer support.
What problems did you have?
Which category do you fall into also:
1) Can't find any other bank to accept your offshore company?
2) Hoping to avoid CRS?
There is no other reason anyone would go near this substandard opaque shell bank operating in a bankrupt third world country . None of the bankers are actually in Puerto Rico....why is that?
