Voting
All people must obey the laws whether they are citizens or not.
The US Government expects certain responsibilities form the US citizen in return of the citizenship status. Among the responsibilities, the most important is filing in the taxes regularly. They should file in taxes for the income that they earn even while residing out of the US.
If one of the parents is a US citizen, the child is a natural born US citizen. Yes, they can run for president.
A US citizen should abide by the laws of the country and respect its principles, Constitution and founding fathers. The main responsibility would be to rise to protect the country at any situation. Voting in the elections is one direct form of showing the duty and responsibility of a USC.
One responsibility that is only for US citizens is holding the office of the President of the United States. A person must be born in the US to be president. Voting is another thing that only citizens can do.
