On the one hand, I have total sympathy for those people because the immigration system is screwed up.
On the other hand, I feel it's important to point out (and for people to acknowledge) that getting into the U.S. compared to getting into a lot of other countries, like the U.K.
In my limited experience (helped brother with getting his Mexican wife into the U.S.) getting into the U.S.A. is a cakewalk by comparison. For another interesting example, I have an uncle who lived in the Netherlands for years on a 'provisional visa' (or whatever they called it) and they kicked him and his family out as soon as he didn't have a job.
Also, I do not understand why people cannot say 'illegal immigrant'. Because they are an immigrant, who is here illegally. Most other countries deport people immediately for that.
