A Sikh-Canadian group is slamming the long-standing immigration policy that forces people with the surname Singh or Kaur to change their last names.

Jasbeer Singh, of the World Sikh Organization, said the policy is incredibly out of synch in this day and age.

Immigration Canada sent a letter to Jaspal Singh stating "the names Kaur and Singh do not qualify for the purpose of immigration to Canada." (Click the link, right, for a larger, PDF version.)

"The reason we should be concerned is this is a very sneaky attack on our individual rights and freedoms and persona," Singh said. "Today they are challenging or don't like Singh or Kaur. Tomorrow they will not like Mohammed. And how soon will it be before they are asking all Browns and Smiths to change their names?"

The policy came to light after a Calgary woman waiting for her husband to arrive in Canada learned her husband's application to become a permanent resident has been delayed for well over a month because of his last name.

The Citizenship and Immigration department says the policy to ask people to provide a third name has been around for 10 years. It's used only in the New Delhi visa office and does not apply to any other last names.

Karen Shadd-Evelyn, a spokeswoman with Citizenship and Immigration Canada, said the reason for the policy is that it helps officials with the paperwork and allows them to identify people's files quickly, efficiently and accurately.

"You can imagine you wouldn't want your file to be confused with someone else's," she said.

Singh and Kaur are common names in the Sikh community. In a tradition that began more than 300 years ago, the name Singh is given to every baptized male and Kaur to every baptized female Sikh. There are millions of Singhs and Kaurs around the world.

Shadd-Evelyn said that while the department recognizes the tradition of having the names Singh and Kaur, it's their understanding that it is already a common practice for people in the Sikh community to have a third name.

"Generally, when we ask for that, they are accustomed to that and are used to providing a third name," she said. "They have it. It's not something that they're just making up on the spot."

Immigration lawyer Peter Wong said the policy is enforced only some of time. None of his clients has ever officially complained, he said.

"Most people don't find it worthwhile to do and are, quite frankly, scared that they're going to be hurting their immigration applications for their loved ones."
