Hi
My sister in law, is living in Pakistan and want to visit her canadian citizen son in Toronto for a year on visit visa.She stays at home and does not work .
Canadaian embassy in Pakistan denied to give her a visit visa for canada twice,without telling any specific reasons.Now whe is thinking to visit Toronto by getting a Multi visit visa from Pakistan and go to an other country,like usa/uk and then from there to visit Toronto.But I and she does not know how to apply/get a Multi visit visa from which embassy,from USA,UK,Sweedan 
What are requirements to apply and get a Multi visit visa to visit USA or UK or Canada via USA /UK 
Her son can show proof of support for a Multi-visa. 1. She still needs a TRV (visitor visa) to get to Canada.
2. The letter of refusal states exactly why they refused her TRV in Isbad.
3. If she was refused in Isbad, the chances of her getting a TRV at another Canadian office are nil.
4. There is no such thing as a multi country visa. The discussion is about Multi entry visas to Canada.
