Hi, everyone. I have some problem with the form IMM 1344 7b. My husband who is a sponsor and be sponsored to Canada before, but he became citizen at 2007. He didn't kept the paper about that. How should I find out his UCI number? All we have are his citizencard and passport. On his citizen card it shows B1234567, it's the UCI number the form asker for? But it's only 7 numbers and I'm not sure. Please help me! :'( :'( :'(
