I repeat my previous statement again !!!
Dojetdriver, take my advice seriously, PLEASE! Never ever, even consider going to Korea as a F/O. You will be done for the aviation business pretty soon after. Subservience is not for everyone, but overthere you are expected and required to do so. The american culture has nothing, I mean NOTHING to do with the korean one. Even the local F/Os love flying with the foreign captains.
