Two Calgary area residents have been charged with immigration fraud, officials said on Monday.

The man and woman, who were arrested last week, face three counts under the Immigration and Refugee Protection Act.

The charges follow an 18-month investigation by the Canada Border Services Agency.

Officials said the pair came to Canada in 2008 as visitors and then made successful applications to stay here — under different identities — a year later.

A court appearance was set for next week.
