Dreviator ,
Global Vectra does have Bell 412 s and I think they aren't recruiting for any expat drivers for them .
They did hire some expat Captains for the 139 s a few years ago and more recently have been giving their experienced 412 Captains the dual AW 139 ratings .
Methinks the Middle East ...... Abu Dhabi Aviation , Falcon or Gulf Helicopters may be your best bet .
Happy Hunting ......
