根据几个因素决定：1 PR申请递交至加拿大境内的case processing center 2 递交PR同时，同时申请了工签。这种情况下不用申请延期
In situations where an applicant who has visitor status submits an application for permanent residence to a case processing centre in Canada and, at the same time, submits an application for a work permit [pursuant to paragraph R207(b)], the visitor may be considered to have requested an extension of their temporary resident status [in accordance with subsection R183(5)]. They are considered to have implied status as a visitor, until a decision is made on their work permit application.
