I have a friend that's currently living in Yemen. I live in the United States. He's trying to get into Canada as soon as possible because of the war in Yemen. He has a phd in computer sciences and he's also looking for work. He hasn't done anything yet, no applications or forms. What does he have to do? Can he get into Canada as a refugee if he's still living in Yemen? I need some detailed information for him and I can't find the info he's looking for. What should his first steps be?
