Just an idea, which might work. If your husband applies for a new passport back home-say he lost his old one- then he should get a new one with a new number, so if the bank have put a ban on him, it would be with his old passport and passport number, and id imagine its the passport number that gets flagged when a person re-enters, not their name.
Just something to think about. ;) And keep the old passport too, in case he needs to leave a passport at the police station for any reason, he will always have the other one to make a quick getaway if need be.
Obviously his residents visa will not be in the new passport, but he can always come in on a holiday visa until he gets sorted. Not sure if his name will show anything on immigrations system though, i cant imagine it would. Everything should be linked to passport numbers.
