Well on this one I can speak from personal experience! I did indeed write that my reason was to stay with my common-law partner until we had passed the 12 month mark and I could then apply to change my status accordingly. Please note I did also provide all the required documentation including a copy of my return ticket.
When you think about it, if CIC provides that you can
1) extend your stay from within Canada, and
2) allows you to apply for PR on the basis that you have lived in Canada with your partner for at least 12 months
then I guess it's logical that it's an acceptable reason to stay here! :-)
Hope that helps.
Thanks but now the situation is I am offered a job in canada, I am debating if I should go to Seattle and get my work permit..or go back to Singapore?
