@ fprince...
nope...she didnt receive it yet....she landed on july 1st....so she probably has to wait for anothing couple of weeks...
how about ur wife? did she rcvd her pr card?
i guess it is probably a system error and u have nothing to worry about...but if u r more concerned in regards to the duplication, ur best option is to call the call centre and advise them about this
keep us posted and good luck with the process :)
