Yea that's what I'm thinking...nothing since Nov, they sent a "prearrival service'' a day after the interview, and then nothing since. But now they asking for a "prepaid courier coupon" to be sent in...don't know what to expect now
A prepaid courier means that they will sent you back the passport with the visa on it .. Congratulations dear

Please share with us the questions they asked you in the interview as some of us will have an interview so it may help ..Thanks
