Answer:
As a permanent resident, you are not eligible to register or vote in national, state or local elections that require a voter to be a U.S. citizen. But what if you still want to get involved in the political process? Thankfully there are other ways you can get involved.
Legal permanent residents are allowed to contribute financially to political campaigns in the U.S. You may also volunteer your time or services to the campaign. Serving as a poll worker is unfortunately not an option, because you must be eligible to vote in the county where you would be working the polls.
