I am a couple of days away from sending in my spousal sponsorship visa application (inland). I, the applicant am currently in Canada on a 2 year CIC work visa which expires in 1 month from now. Should I apply for some kind of extension to keep my status in Canada, or is sending in my other application enough for me to stay? If sending in my visa application is enough for me to stay, will it matter if my current work visa expires before my application is received (but sent)?
