Twenty years ago, there were 50 recorded Haitians living in Chile; now there are 200,000, or about 1 percent of the population. They are all over Santiago and their presence is a hot political issue there. But how they could get from Chile to Texas is another matter - it is heaps, literal heaps of miles to cross unless you can afford to fly.
Many are bused up from Chili etc. like trade routes it’s not hard by those who profit from getting these people up here.
