That document (that you've poorly linked[1]) puts the percentage of British immigrants at 9%, Irish at 10%, of German at 18%, and of French at 0.9%. All those numbers are totally meaningless. The population of the US as a whole that was foreign born was 14.7%. That too, is meaningless. In the 1890 census, closest to when Tesla was naturalized, it was also around 15% [2].

I don't know what narrative you're trying to debunk, because 15% year by year for years and years is high. The UK, which is a top destination for immigration, has never been close to that number until very recently. [3] But really, what I actually find weird is that you're trying to debunk some narrative.
