Expats from countries where the vaccinations are being handled by national authorities would not have this problem. And US expats who mainttained a state of residence back in the U.S. will not have this issue either. But for us US expats who no longer have a state of residence it seems to be a problem. The distribution of the vaccines are being handled on a state level for their residents. And presumably each state will want to make sure folks aren't coming in from out of state to deplete their limit supply. So presumably one will have to prove state residence. But wiith some 10 million US cits living abroad somebody must have thought that some of them might want to be vaccinated as well, and prefer to do it back in the U.S. rather than depend on what and when they might be able to get it where they live. The flip side of this question is how are the DR authorities going to ration what vaccine they get (whenever that might be). Will the limited supply be reserved for Dominican citizens? Or is it likely to be a formal system that prioritizes Dominicans and an informal system based on who can pay the most?
