You are ready to take risks and are not afraid of sudden changes. In the US, short-term contracts are common and it is common to change career paths frequently.
For example, it is normal for Americans when a boss leaves in the middle of a project, finding a better-paid job.
Also, in the US, more often than in Russia, changes occur in the middle of a quarter, school year, or project. There is also unpredictability in visa issues – you never know whether your work visa will be extended or not. You have to not lose heart from changes, and look for legal options to stay in the country.
You are law-abiding. You do not try to find loopholes to circumvent the law in your favor.
You are tolerant. If you are calm about the fact that another person may have opposing views on anything, most likely, you will be comfortable in the US.
