Unlike permanent residents, green card holders, citizens are granted the right to vote. Citizens may vote in all federal (national) elections, but right to vote in state elections is determined by the laws of each state. For example, some states deny convicted felons the right to vote.
#2 U.S. passport
All citizens have the right to a U.S. passport. A U.S. passport allows you not only to travel internationally, in many cases without needing a visa, but also to re-enter the United States freely.
#3 Bring your family to the U.S
Citizens have the opportunity to petition for family members to join them in the U.S. As a citizen, you can petition for an immigrant visa, a green card, for your spouse, children, parents and siblings. These are the Immediate Relative Immigrant Visas and the Family Preference Immigrant Visas. The IR visas are unlimited, meaning your relative will experience only a short wait to get their green card, not having to wait for a visa to become available. Permanent residents may only petition for spouses and children, not parents or siblings, and these immigrant visas are limited.
#4 Not be deported
Though green card holders have permanent immigrant status, they still may be deported for such reasons as committing a serious crime. Citizens hold a much stronger place in U.S. society and may not be deported.
#5 Citizenship for your children
The children of citizens have the right to citizenship themselves. All persons born in the U.S. are automatically granted citizenship. But, even if the child of U.S. citizen is born abroad, he has the right to claim U.S. citizenship through the simple process of registering the birth before the child turns 18 years of age. Even if the child does not claim citizenship before his 18th birthday, he may become a citizen through naturalization. Children of parents who naturalize also have access to citizenship by first becoming permanent residents through the IR-2 visa and then naturalizing themselves.
