12,500 is not a decent salary these days for a man at least. I am an Asian woman from the subcontinent, on father' sponsorship working in a Q-company. I get approx 12000 per month but men on the same position as mine my company get almost 15 if they are single and around 18 if they are married. So the verdict is that the amount they have offered you is peanuts for a family man.
