Ask HN: Advice for emigrating from Third World

Hello HN. I am a software developer living in a Third World country. I would like to migrate with my family to another country because the situation in our country has gotten worse over the past couple of months. I do not wish to raise our children in this environment and I don't see things improving in the foreseeable future. I also want to provide more options for our kids. Dual-citizenship and passports will open doors for them in the future. We are considering Australia and Canada, because we have family and friends there. I want to ask for advice from anyone who's made a similar move or anyone familiar with the situation in the above countries. some questions - what are the dev job prospects like in the above places? - is hiring ageism widespread (I'm in my late 30s)? - are there any particular places you'd recommend or avoid? - are there other countries you think we should consider? There's lots of information out there but I want to hear your perspective.
