I'm in the process of gathering everything to sponsor my Korean wife. I've lived here in Korea since the end of 2007, and I contacted CRA to find out about my option c printout. Because I have been a non resident and not filed taxes since the 2007 tax period, I was told that the option c for that year is the only one I can get. The only way to get a more recent one is to file a tax return for each year between 2008 til now. What are my options for the application process? I will be receiving the 2007 option c very soon and was going to include a letter explaining why I don't have a more recent one. Will this be enough? I also have the letter from my employer showing my salary etc. This is my biggest concern so far.
