The 47-year-old doctor-turned writer is also trying for a permanent residency in the country. Her visa is valid till August 16. Her application for granting a permanent residency in the country has been hanging in balance for years together.

Official sources said the government has already made it clear that Taslima's visa cannot be extended beyond August 16, 2010 as her travel document had been issued under the category (miscellaneous).

Taslima, a Swedish passport-holder, had sought visa under the miscellaneous category in 2005 and it has since been extended initially for a year and later for six months. The visa under this category cannot be extended beyond five years.

She has been conveyed that she should seek a fresh visa from a third country after which she could visit India again, the sources said.

Taslima, who has been in and out of the country after she was dramatically bundled out of West Bengal in November 2007 in the wake of protests by radical Muslim groups, came from London in the wee hours of Sunday last and was immediately whisked away to a safe location.

The future plans of the writer, who shot to fame with her controversial book 'Lajja' in 1994, were not immediately known.

The writer has been told that she could stay in some other country for a few days and later apply afresh for the visa under the same category, pending her request for a permanent residency in the country, the sources said.

The writer had earlier expressed her desire to visit Kolkata but it has been turned down on the ground that radical elements may try to harm her, the sources said.
