Do you think the government is going to come and forcibly remove them from the country if they don't want to leave? The state department has warned people against going to the country for over a decade, and likewise has issued advisories to all of the expats living there the entire time they're there. Anyone with any sense got out of the country a while ago. The vast majority of those left are foolhardy individuals who didn't think it would get as bad as it is.
