If what you're asking is how long can a Polish immigrant stay for in the UK, the answer is: infinitely. Both the countries are in the EU and EU nationals can visit and stay in each other's countries without limits. If an EU immigrant, including Poles, were to live in the UK long enough (a few years), they might be eligible for the status of a Resident or - to apply for a British citizenship.
If you have dual nationality, you can stay for as long as you want to and can afford.
A Polish national is REQUIRED to have a visa to enter the U.S. So, without a visa, a Polish citizen cant enter the US at all- period (never mind how long he can stay).
like 1 or 2 weeks
Indefinitely
Yes, some Polish people do live in the UK.
In the UK, it will stay for about two months :)
Polish immigration is not seen as a problem that needs a solution in the UK.
How long a UK resident can stay abroad is up to the country the person is visiting. For example, a UK resident can stay in the United States 3 months without a visa, and longer with one. Some countries will only allow him to stay there two weeks, and many countries require the UK resident to obtain a visa before traveling. The visa will specify how long he may stay.
A few days, maybe a week. to avoid this, use a base coat underneath your nail polish.
