There has also been a drop in Pakistani and Ethiopian numbers, the Times of Oman report said quoting latest data issued by the country's National Centre for Statistics and Information (NCSI).
The NCSI data shows that there was a dip of 0.1 per cent in the number of Indian workers in January this year when compared to December 2013.
While 599,473 Indians were working in Oman in December last year, the figure for January this year was only 598,674.
According to the report, in November 2013, the number of Indian workers was 600,349, but it fell down to 599,473 in December.
"Since the first month of this year, the Ministry of Manpower imposed a temporary ban on different job categories for expatriates. In addition to this, new regulations have been imposed for visa status. These might have been reasons for the dip in the number of expatriates, mainly Indians," Deepa Sudhir, one of the embassy panel lawyers, was quoted as saying.
"The government's decision to reserve certain jobs only for Omanis as part of the Omanization process might have led to this situation. Changes in the visa status might also be an additional reason," ShajiSebastin, a Muscat-based social worker, told the newspaper.
