There is a guide to American Culture for Russians visiting the US. Here are three that may make you chuckle:
1)  Women play a greater role in business. Often they insist to be treated exactly as an equal and not as a lady.

2) As a rule, a social invitation will only be on a weekend, and you don’t have to prepare for anything extravagant.  Everything is the same as ours, only with far less booze.

3) “See you later” should not be taken literally.  This is a courtesy statement and no more.
