How to say "being" as in "Being jewish" I've always had some difficulty trying to translate the english "being" as in "being Christian" or "being American". I'd like to say 
"in the U.S. being Jewish isn't difficult." 

Should I say 我在美国成为犹太人并不难  ?

I feel like 成为 in this instance implies becoming - which is not quite what I am trying to imply.
I think the word you're looking for is 作为

in the capacity, character, or role of; as
作为你的朋友，我得劝劝你
As your friend, I have to give you some advice
你作为领导，就要以身作则
As a leader, you should set a good example for others -A Chinese English Dictionary

This is basically the equivalent of as in English - which I think is what you're looking for with 'being'.
being Jewish 作为一个犹太人
being American 作为一个老美
being Christian 作为一个基督徒
