The compliance department at IB-EU/UK/IE are *extremely* painfully slow. Something that should take a day can easily take months.
They also offer *very* little communication/support. It's effectively: Give us this information. *disappear for 3 months*. Done.
I've had to deal with them on more than one occasion and I would say it is such a weak part of IB's operation that I've actually moved assets out of IB to mitigate risk. (They will put a hold on your account until THEY finish their paper-work, and this can easily extend into multiple months).
