回复：加拿大国籍真是麻烦,回趟国还得签证.

what is the problem with you? Do sth useful. Do not just whinning here. You are a mature woman with a master degree. If you do not know what to do, no one can help you out. It looks like you are doing nothing but cursing Canandian citizenship or PR. It is a shame Canada has you as a PR---loser.
