Hello everyone, I'm a Canadian citizen and have started paperwork for my wife-to-be who is currently in India. I have 2 questions: 1- She currently doesn't have a last/family name. Just first name only.. and it is same in her passport. On Form IMM 1344E, the field for last name.. I've left it blank but the document will not allow itself to be saved. -- Am unsure what to do. I tried N/A but it doesnt accept / either. 2- Also I have no idea what this UCI/Client ID is. I am thinking about putting in my Canadian citizenship certificate number in there. I have looked in my form IMM 1000 from when we landed over 25 years ago and I dont see a UCI/Client ID number. There is a number started with B and another one started with W. I have tried both of those but the PDF doc (IMM 1344E) doesn't accept it. Any help will be greatly appreciated. Thanks.
