Her son Mazdak Dilshad Baloch is already camping in India. She was supposed to address an outreach organised by the RSS-backed India Policy Foundation earlier this month but could not do so for failing to secure visa on time.
"Things are changing rapidly at the international level. You have seen in the United Nations...Other countries are coming forward to support the Balochistan issue," Prof Baloch, who lives in self-exile in Canada, told reporters after arriving at the IGI airport.
"She was not denied visa. It just got delayed so she could not address the October 1 event. Now, both of us will be attending events both in and outside Delhi for the next one week or so," he said.
The Baloch cause for freedom has received a major diplomatic push since Modi brought up Pakistani atrocities on people of Balochistan and PoK in his Independence Day speech.
Another prominent exiled Baloch leader Brahamdagh Bugti, had approached the Indian Embassy in Geneva seeking asylum in India last month.
