what are the differents opinions about immigration in the usa ? thank you for your help ^^

Some people think that it can be a benefit for the English economy (for the labor...)
- find a safe country for the immigrants is the duty of America because it is ''a nation of immigrants'' (cf statue of liberty).

But other people think ;
- they take the jobs of the inhabitants
- they lose their cultural identity (spanglish)
- the immigrants could bring violence so they are dangerous
- there is also the illegal immigration (the fence (Mexico / USA)/ minutemen to avoid it.
