Hi borrowdale,
Thank you. I'm really happy that my interview letter came through. Did you receive a letter for an interview? As Justina asks, which letters did you get? If it doesn't say "An appointment concerning your p.r. in canada has been scheduled." Underneath should say: Date, time, where. If it doesn't say this then, you probably have your approval letters.
The last line on my letter says "All applicants in your family must attend this interview." I suppose this mean, since my husband applied to be my sponser and I am the one being sponsered, that must mean, both of us are required to attend the interview. So that means your spouse MUST attend. If your spouse is not available to attend your date, I would call or if someone is calling to sched. an interview I would explain to them. They aren't going to tell you, "OH you can't land now." I'm sure they will work with you to help make landing convenient for you. Your landing letter should state all the items you need to bring with you and how much to pay.
Hope this helps. Good luck.
