You really need to get to VJ. As you WILL have an interview if ur going for the
K1 Fiance visa. Will be either in Vancouver or Montreal, depending where one lives in Canada. The k1 process can take anywhere from 6-9 months, maybe a bit quicker if ur going through the Vancouver Consulate.
But you really need to goto VJ and understand the K1 process. It has super helpful. Best of luck
