I perfectly agree and know where your coming from. I believe change is always necessary. You can always come and live with your parents and study here for exams. But as far as training and on the job atmosphere is concerned , it depends from group to group. Some departments are termed as having some degree of ethical flexibility however some are quite strict in their code. I would would advice not to over think and go for it . Foreign services is a really nice option. I wish your best of luck... and do what you feel is right not considering the after effects.
