Some personal insights
U.S culture varies for everyone depending on which culture you belong to. Coming from Pakistan, U.S culture seemed entirely different to me especially the social norms. But the thing is that being internationals it is in our best interest to adapt the culture as soon as possible and get used to it to feel oneself as a part of where we will be living for the next couple of years or more. Things become easy if you try to make as many friends as possible and the key is that "Be the first one to introduce". People here like to help but you want to be able to ask for it. So don't be shy and just express yourself, you will be adored.
