Which countries in the world give foreign immigrants the right to vote and stand for election?

Basically, all countries in the world will enjoy a certain degree of political rights when they acquire nationality. The degree varies from country to country. Having nationality means becoming a citizen of that country, and the criteria for judging whether a person is a citizen of that country are only part of the criteria for voting and being elected.

Countries have different political policies on immigration. For example, in the United States, non-American-born citizens (that is, immigrants) do not have the right to be elected president, but they have the right to be elected members of the Senate and House of Representatives and heads of state (governors).
