Hello, i have applied for SIN in march, went in person to service canada however they are unable to issue my SIN and said that there is something wrong and need some details from immigration and marked my request as urgent. Even after one month they are telling the same thing stating that an agent is working on your request meanwhile i called immigration and checked with them but they said all looks good so i again called service canada but they are telling the same thing now it is nearly two months and still no update yet. Could anybody help me on this. What to do how to proceed further.
