@coldjoint,
By all means, keep your head in the sand. Saudi Arabia is a major trading partner, and owner of much real estate within north America.
At last count, there's over 1200 mosques within the US of A, although the Muslim population is estimated to be only 3% of the total.
And you didn't answer the other half of the question; who are these "immigrants"? America was born on immigration.
The wealthiest-ever diaspora (migration) to the US of A, was from Iran post-revolution.

According to various sources, in 2010, there were an estimated four to five million Iranians living abroad, mostly in North America, Europe, Persian Gulf States, Turkey, Australia and the broader Middle East.[7][8][9][10] For the most part, they emigrated after the Iranian Revolution in 1979.[citation needed]
Their combined net worth is $1.3 trillion (2006 est.)[7][11][12] In 2000, the Iran Press Service reported that Iranian expatriates had invested between $200 and $400 billion in the United States, Europe, and China, but almost nothing in Iran.[9] In Dubai, Iranian expatriates have invested an estimated $200 billion (2006).[13] Migrant Iranian workers abroad remitted less than two billion dollars home in 2006.[14]
