Work Authorization: Green Card holders are authorized to work in the United States without the need for a separate work visa or work permit.
Travel: Green Card holders can travel in and out of the United States without the need for a separate visa, provided they do not stay outside the country for an extended period of time.
Education: Green Card holders can enroll in any educational program, including colleges and universities, and may be eligible for in-state tuition rates.
Social Security and Medicare: Green Card holders are eligible for Social Security and Medicare benefits after paying into the system for a certain period of time.
Path to Citizenship: Green Card holders may be eligible to apply for U.S. citizenship after a certain period of time.
Sponsor Relatives: Green Card holders can sponsor their relatives to come and live in the United States, subject to certain requirements.
Legal Protection: Green Card holders are protected under U.S. law and have access to the U.S. legal system, including the ability to petition for themselves in immigration court.
 
Overall, holding a Green Card provides a number of important benefits that can help individuals build a stable life in the United States, including access to work, education, and social services, as well as a path to permanent residency and citizenship.
