Islam in the Americas
Islam is a minority religion in all of the countries and territories of the Americas, around 1% of North America population are Muslims, and 0.1% of Latin America and Caribbean population are Muslims.

Suriname has the highest percentage of Muslims in its population for the region, with 13.9% or 75,053	individuals, according to its 2012 census. However, the United States, in which estimates vary due to a lack of a census question, is generally believed to have the largest population, with approximately 3.45 million Muslims living there, about 1.1 percent of the total U.S. population. 

Most Muslims in the former British Caribbean came from the Indian subcontinent as indentured servants following the abolition of slavery. This movement also reached Suriname, although other Muslims there moved from a separate Dutch colony, which is now Indonesia. In the United States, the largest Muslim ethnic group is of White/Middle-Eastern region/Arabs].  However, in South America, the Muslim population is mainly composed of upper-class immigrants from the Levant, including those from Lebanon and Syria.

Immigrant Muslims in America 
In regards to Immigrant Muslims in America: at first, a population of African Muslims entered the United States as slaves, and at the next stage, while the immigration laws to this country eased the conditions for accepting immigrants from all over the world, another population of Muslim people entered there. In the last 25 years, new waves of immigrants as well as the tendency of a large group of American blacks to Islam have caused an increase in the number of Muslims in America. According to one of the professors of the University of Massachusetts, USA, the number of Muslims in America is estimated to be close to four (4) million people, and is appraised that two thirds of this population are "immigrants and their children" apart from Muslim Americans.

In 1991, more than 100,000 immigrants entered the United States legally, most of whom were people (mostly Muslim) from Bangladesh, Pakistan, Iran, Lebanon, Egypt and India. Also, another unknown figure should be allocated to illegal Muslim immigrants who entered the United States this year.
