Wow, I can't believe you're honestly trying to compare the number of muslim immigrants to the US to muslim immigrants in Europe. There's gotta be some massive cognitive dissonance to not realize how disingenuous that is. The vast majority of Muslim immigration to Europe isn't from asylum seekers. It's economic.
The biggest concentration of muslims in the US is in New York city, and it's around 70k people. London alone has 600k muslims. And as the previous link demonstrated, muslim immigrants to the US are proportionally much richer and better educated. You don't seem to want to grasp the differences because you want to score some sort of ideological victory for american exceptionalism, frankly.
