Yes, they are US citizens, so are entitled to a voting congress member.
No, they might be US citizens, but they'll never be murican. Or, I have a good reason in the comments....
This is really stupid. They are US citizens, but for some reason they are not entitled to voting house members? Its one thing for the senate, since they're not states, but there is no reason people should be suppressed politically for living outside our borders. People in Guam, Samoa, and Puerto Rico should be divided into districts.
US laws apply to them and if they have to abide by them, they should be able to have their fair say. Puerto Rico, US minor outlay Islands, Guam, ect; they should all have their say. District of Columbia got the right to vote for presidential elections in 1960-'61, and that's a start but 50 years later we still need everybody to be equal.
If they have to follow our laws, they should have a say in what those laws are.
