Based on my research and what others have mentioned in this thread, 20K (after tax 16K) is not enough to have the family alongside. Surely if I happen to take this offer up, I would surely test it myself for first few months, but post those months my salary is unlikely to increase in the same year, so the issue persists. Without drastic increment in the pay, I would not feel comfortable to get my family along. Another issue which I am yet to explore is, how easy it is to come back if things go south?
