Oman's foreign workers send an estimated US$10 billion annually to their home states in Asia and Africa, more than half of them earning a monthly wage of less than US$400. The largest foreign community is from the Indian states of Kerala, Tamil Nadu, Karnataka, Maharashtra, Gujarat and the Punjab, representing more than half of entire workforce in Oman. Salaries for overseas workers are known to be less than for Omani nationals, though still from two to five times higher than for the equivalent job in India.
