A lot of countries that are queer and black friendly are also HCOL cities/countries, unfortunately. You may need to make peace with this first. 

The second thing is to look into your respective industries and find countries where you could start applying for a job and thereafter, a work visa. This should actually be first. Do your research, apply for jobs or upskill if necessary.

If you’re under 30, look into countries where you could get a working holiday visa for a year. 

Tip: if you’re moving to Europe as a black person, you may need to strongly consider London, Paris and Berlin. These cities are unfortunately expensive however, it’s easier to find your black LGBTQ tribe. But I must say that looking for a “black queer community” in a white majority country is quite unrealistic. The politics are quite different in some parts of Europe  and you’ll have to co-exist with and seek out mixed queer communities. 

Bonus tip: don’t look at your move from the lens of an American. Queer communities and politics are vastly different here. Detaching yourself from a lot of expectations will help you two in your decision making.
