A Green Card is a Permanent Residence Visa for the United States. The residence card will give you legal right to study, work, and live permanently in the United States. Green Card holders receive health, education, and several other benefits. If you are selected to receive a Permanent Residence Card, you can apply for United States Citizenship at a later time. The Green Card does not affect your present citizenship. You and your family could be lucky winners if you act now and apply today.
