India's West Bengal state government says it has had no contact with Delhi about granting a controversial Bangladeshi writer Indian citizenship.
Ms Nasreen faced death threats in her homeland
An unnamed state official had earlier told the BBC that the presence of the author, Taslima Nasreen, in Calcutta could stir up religious tensions.
West Bengal authorities had shared this fear with central government, he said.
But state Home Secretary Amit Kiran Deb said: "The government of India has not even asked us for our comments."
He told the BBC he had no idea whether Ms Nasreen had even applied for Indian citizenship.
Any decision on residence or citizenship would be made directly by government in Delhi, which may as part of the process consult the state government at some point, he said.
But he added that it had not done so in her case.
Taslima Nasreen fled her native country after Islamic radicals alleged her writing was blasphemous.
She is currently living in Calcutta on a visitor's visa and has said she wants to make the city her home.
Ms Nasreen, a doctor-turned-writer, rose to prominence in 1993 after her first book, Shame, ran into problems.
She fled Bangladesh shortly afterwards, following calls for her execution.
Islamic radicals were incensed at comments she is said to have made to an Indian newspaper calling for changes in the Koran to give women more rights. Ms Nasreen denies making the remarks.
