"A lot of them were also kept in police stations of areas where these raids were conducted," he said, adding officials from the embassy will be visiting these police stations soon.
Nair said the crux of the problem is people coming on domestic visas and working elsewhere.
"Kuwaiti government wants to send these people (with visas to work as domestic help) back to their sponsors because they are not supposed to work outside the household. It is a violation of (Article 20) their visa rule," said Nair.
He, however, said the embassy has raised concerns about the situation these workers find themselves in and has written to Kuwait's Ministry of Interior and other local government officials relevant to the matter.
The embassy had managed to track down and collate documents of around 650 of them, Nair said.
All those with valid documents would be released, while the remaining might be deported to India, he said.
The Indians are among the more than 2,000 people who were arrested last week for expired visas and involvement in crimes during impromptu security checks.
Most of the arrested Indians are from the southern Rajasthan districts of Banswara, Pratapgarh and Dungarpur, reports Jaipur-based journalist Narayan Bareth.
Rajasthan chief minsiter Ashok Gehlot has written to External Affairs Minister SM Krishna asking him to help secure the release of the men. Krishna has sought a report from the Indian Ambassador to Kuwait.
