> I would be interested to learn if there are any non-profits that run campaigns that aim to educate and inform the public.

There are thousands of such organizations.

> if they stop immigrants from coming and stealing their jobs. Which I suppose is a reasonable conclusion for an uninformed person to reach.

Unions and all professionals organizations believe that decreasing competition for jobs results increased salaries. We also believe that decreased competition in other products results in higher prices. Are they wrong or is immigrant job competition different?

Yes, some immigrants bring skills etc, but not all, and you didn't make that distinction.
