Answer:
The culture of the Jewish Orthodox in America is similar to the culture of the Jewish Orthodox in other places like Israel or Russia.
The Jewish Orthodox in America are concentrated in the Northeast, particularly in New York and New Jersey. They mostly keep to themselves, and follow different branches of Judaism, like Hasidic Judaism, and Haredi Judaism.
They follow customs typical of orthodox judaism, like dressing in black, keeping long hair and beards in the case of men, and having large families. Women often do not work, and all of them keep the sabbath strictly (meaning that none of them work on saturdays).
