The assurance by the High Commissioner Vijay Thakur Singh came in the wake of Sunday's riot in Little India, triggered by an Indian national's death in a bus accident.
"The High Commission has always cared and will continue to care for the welfare and well-being of Indian citizens in Singapore," Singh told PTI.
Singh said she will visit a number of dormitories housing Indian workers over the next few days to assure them of the Mission's support.
Singh said she was assured by Singapore authorities that those who had done no wrong should not worry.

But, those who broke the law would have to face the consequences, she added.
Indians working in Singapore must abide by the law of the land and the rules and regulations of the country must be respected, Singh stressed.
She said lawyers were coming forward through the Law Society of Singapore to make legal assistance to those arrested in connection with the riot in Little India.
The riot was an unfortunate incident, but it was not premeditated, Singh said.
Around 400 South Asian migrant workers were involved in the rampage that left 39 police and civil defence staff injured and 25 vehicles -- including 16 police cars -- damaged or burnt.
Singapore previously witnessed violence of such scale during race riots in 1969.
After visiting Indian workers at a dormitory last night, Singh said no discontentment has been discerned among Indians working in Singapore.
But she noted concerns of some individuals related to wages, benefits and compensation.
Prime Minister Lee Hsien Loong has warned that trouble-makers will be dealt with "severely".
