Question

2. The goal of the charity was to help its target demographic integrate into the U.S. society.

======================================================
Do we have to use U.S. society or the U.S. society? Do we need to put 'the' before U.S. society?

Answer 1

You can use it or not, as you wish. I think without ‘the’ is more usual, though.
