St. Kitts still most popular and well known.

The EU only has one citizenship by investment program left - Malta. It’s almost a million euros outlay of capital.

There are still a few EU golden visa programs (permanent residency) - Portugal (potentially on its last legs), Italy, Greece, Spain.

I’m not a huge fan of EU permanent residency by investment if the client’s goal is CITIZENSHIP, because the path is usually long (5-6 years) and the prospect of ever being naturalized is uncertain at best.
