Hi
Thank PMM so much for your answer!
At first I want to sponsor my older son but after his arriving and getting Permanent Resident Card he will come back to continue his education .After I want to sponsor my wife and younger son when he will complete high school. May be I don't unerstand you right and something is wrong. Please explain me can I plan like that ? Please excuse me for my English.....
1. In a sponsorship every one has to be examined (spouse, children) whether they are emigrating or not to ensure that they meet the requirements.
2. I made an assumption that you when you emigrated that you declared the spouse and children or you married after landing.
3. You can;t just sponsor the son.
