The Union Home Ministry has extended the visa of American historian Peter Heehs by one year, according to sources in Sri Aurobindo Ashram here.

Mr. Heehs, whose book on Aurobindo had created a controversy, received an oral communication to that effect from the Foreigners' Regional Registration Office (FRRO) in New Delhi on Friday, the sources said.

Mr. Heehs, whose visa was to expire on April 15, had booked tickets to the United States when the order came. He is expected to receive the papers soon, the sources said.

Earlier, the FRRO had decided not to extend his visa following complaints from Ashram followers that they were hurt by the contents of his book. However, the decision was reviewed following an appeal by several personalities, including Union Ministers.
