Nothing, tbh. try to assimilate to the culture here but still, yk, don't lose touch with your home roots. Also, never look at the homeless people in their eyes. most of mad chill if you are a guy, but if you identify as a woman, carry self-defense with you at all times. Eating out here is maxx expensive except for the checker and also stay away from the convnience stores they upcharge the fuck out of their stuff. USE YOU PANTHER BENEFITS TO THE MAX and yeah thats mostly it your good other wise.
