What Canadian visa should my fiance apply for?
If your intent is to marry before she immigrates, then you should do so before applying. While Canada permits the sponsorship of fiancees, if she applied, and then you married, this change could slow down the application because the documentary requirements will change from a fiancee applicant to a spousal applicant. Either that, or sponsor as a fiancee and wait until she is granted PR and lands to get married. In any case, you will be applying to sponsor, she will be applying for permanent residence. Start with the IRCC website for forms and instruction guides. You should have no need for an immigration consultant, the forms and guides are quite straightforward.
