Difference Between Green Card and Citizenship

I am quite happy with my green card. Why should I bother to become a U.S. Citizen?
Here are several reasons to become a U.S. citizen:
  • The right to vote
  • The right to sit on a jury
  • The right to sponsor an extended list of relatives for permanent residence
  • Tax benefits and estate planning
  • Access to restricted professions
  • Definite protection from deportation
  • Easier to travel to different countries
  • Run for public office
  • The full protection of U.S. Constitution and laws
