I am a Canadian girl with a Colombian boyfriend. We have been together for 3 years and have applied for a visitors visa twice and declined both times. The problem is, he has no real ties to his country aside from his Mom and brother, he is however the main provider for them. He has no children, no property etc... We have no ill intentions, we simply want him to visit my home country, meet my family, friends etc...but we are at a loss since the applications are being denied and I understand why, I just find it quite frustrating and need some suggestions that could possibly help our case in proving to the immigration officer he will leave once his visa is over. Any suggestions, help etc... will be much appreciated. Thank you in advance.
