Becoming an expat involved considerable expense in uprooting my family and setting up home thousands of miles away. I am living in someone elses country as a foreigner where I do not have the same privilages as the locals, I have to fit in and obey new laws and adjust to a new lifestyle.
Now why would I subject myself to all this inconvenience just to be able to save the same $$$ as I can at home ? I am overseas for a nett benefit to myself compared to what I would have if I stayed home. ie Better aircraft, quicker promotion, more money.
At the moment there are plenty of opportunities around for pilots, why not take advantage of them to improve your position. Your salaries seem very low considering the present job market, I doubled my take home pay by going overseas, you could do the same.
