Its not just a matter of bringing in foreigners, its the type of foreigners that are brought in through immigration. Adding population that is not Western European based, with Judaeo-Christian values, is a sure path to destruction of the US.
Christians are found worldwide, in fact Western Europe has become much more secular - kinda like our country. I will agree we need to ensure the speak english and love America.
Last year my son served on a jury where the defendant did not speak or understand any English; progress was tedious. I was in hospital some years ago with the fellow in the next bed who was Vietnamese; he could not communicate with medical staff. At least he probably had a good reason for being here. I presume things worked out for him.
