In India people are earning decent salaries if you have qualification and experience. To tell you fact Qatar is not that green pasture you may think. Cost of living is very high and salaries are not that good for specially people from Asia. Of course if you hold one of the Canada, UK, USA passport then situation is different. Better first make survey, ask your India friends or have a visit for a week to Qatar before you move.
