Thanks for the advise, but I have a few question if we go to Singapore to get married...
What happens to her status in the Philippines?
Should she forward the marriage documents to National Statistics for change of last name to mine?
What about her passport, NBI, etc?
Should all her legal documents be under my last name?
I would advise not to change her last name after you guys get married... Coz it will take 3 months now to get a passport in the Philippines. SO better let her use her maiden name while you apply ( I would assume she has a passport, right?) .....Legal documents should be all consistent... If you use maiden name for passport, then use maiden name in your application forms

She can change her last name once she is in Canada.
