The immigration is asking about the father of my kids which was unknown on their birth certificates, at my teenage years i was so rebellious and got knocked up twice. Now I married one of my exes before. I received a letter stating that our relationship was not true. Should I get all the letters notarized for all the evidences that we will be providing? as this will be the last chance. I was given 30 days for everything and then they will give the final verdict if not provided. They are also asking for a detailed story for the fathers of my kids. How detailed? My kids are with me here in Canada.
