The DACA program provides temporary relief from deportation for young people who meet certain requirements. If you qualify for DACA, it would allow you to stay in the country for an extra two years.
After two years, you can apply for an extension for two more years. But it is important to understand that DACA is not a way to get permanent residency or citizenship. It is just a way to stay and work in the United States without being deported. If you are eligible for DACA, you will receive a Social Security number and a work permit.
There are a number of requirements that you need to meet to be eligible to apply for the DACA Program. But you must be at least 15 years old to apply. If you are older than 15, you must have come to the United States before you turned 16. There are several other requirements. For more information on eligibility, see this DACA guide.
