It means that you are now a Lawful Permanent Resident of the United States! CONGRATULATIONS!!!!!!
THIS IS NOT LEGAL ADVICE
Leviticus 19:33-34 "When an alien lives with you in your land, do not mistreat him. The alien living with you must be treated as one of your native-born. Love him as yourself, for you were aliens in Egypt. I am the LORD your God."
You should keep an eye on your mail for the next 30 days. If you do not receive your Permanent Resident card by then, you should call the CIS and check on it.
