Ahh OK, thanks!
My sources are a banker at Bison and 2 at BIG, plus my lawyers (reiterated 3 days ago in their office when we were talking about how busy Bison was with new applicants), plus reading all of the forum posts for the last year. A few of the people on this forum clearly know what they’re talking about and the consensus of everyone I’ve ever talked to–backed up by several detailed posts describing woeful missteps and lessons learned–is that Millennium is not FATCA compliant for depository accounts and will not knowingly open those accounts for US persons. They are FATCA compliant for regular banking and will open current accounts for American customers who go through the required bureaucratic rituals.
Good luck with the process!
