Thanks @TheDarkKnightRises - Appreciate your prompt reply. There is a difference of about 20 % (increase) but money is not much of concern or motivation at the moment. What I am looking for is a definite career path.

Do you think if I negotiate on this issue with the HR and lets say they agree, will they honor their words? I know I am bit pessimist about it but Qatar will be a new place for me and I really don't know how else I can ensure about my promotion especially when I am going one step down (if I take this opportunity).
