国内申請のものですが、CICのHPにあるこの文から理解すると、2005.2の新しい規則より、申請中はregardless of your immigration status in Canadaということでよいのか、、私も観光ビザが切れるので迷います。
Sponsorship of Spouses and Common Law Partners Within Canada:
New Policy Announced On February 18, 2005,
the Minister announced a new policy intended to facilitate the processing of spouses and common-law partners of Canadian citizens or permanent residents of Canada, who do not have legal immigration status in Canada.
In accordance with this change in policy, regardless of your immigration status in Canada, you may use the application package Applying for Permanent Residence from Within Canada: Spouse or Common-law Partner in Canada Class if:
You are in a bona fide marriage or common-law relationship with a Canadian citizen or permanent resident
You live with your spouse or common-law partner in Canada
Your spouse or common-law partner wants to sponsor you (and your dependent children) for permanent residence in Canada
