Hello all, I’m the Sponsor but helping out my common law partner for filling out his application form. Should I submit form IMM 5406 acting his representative? We are currently living as common law partner for the last 14 months now and were ready to submit the application. Also I want to mention to hat I am submitting a cover letter stating how our relationship started and how it progressed. And at the end asking them to grant us to be together permanently. Please clarify and help! Thanks in advance.
