Where does one go with one of the weakest passports in the world, no assets, no family connections, and probably only sporadically any skills capable of getting a work visa? I need to get on speed dial whatever immigration lawyer those people had.

I can't find the article but I did read a few years ago most had left to either Mexico or the US. The US had a very favorable program for cubans to enter, work and stay in the country under the Biden admin.

The cuban government via National Office of Statistics and Information admitted it fell by at least 10%, but have not done a census in 15 years. Independent estimates range form 18-24%.
