It probably is to come to the states, I'm sure. Its been ages since I have been to Santiago where she is from but its not a big city like Santo Domingo. Looking it up, times have changed and its a big city only second to SD. So she might not have been living in abject poverty, though you can have extreme wealth and extreme poverty within blocks of each other.
My family that still lives there has remarked that there has been a rise in street crime. Two of my cousins were mugged on the street, and my cousin's daughter was robbed at gunpoint in her house (with her daughters there). So maybe that is another reason she wants to leave. Though Miami isn't exactly crime free.
Thinking about clothes..... I remember seeing some people live in poor (but not the worst) conditions and they always dressed nice.
