With everything in the news about the "immigration crisis" in Europe, and the wave of Mexicans crossing the border into the US, it made me wonder how Americans of the 1920s e.g viewed the huge wave of Italian immigrants (more than 4 million) arriving on the East Coast. Especially considering how they were predomenantly Catholic while America was a Protestant country. Did it spark debates on immigration laws the same way it's doing today? Were they viewed suspiciously? Thanks in advance.
