CSPA Calculator: Find Out If Your Child Can Still Get a Green Card

September 18, 2026

    If your family has been waiting years for a green card, there's one date that matters more than any other: your child's 21st birthday. Once a child turns 21, they can lose their place in line — a problem immigration attorneys call "aging out." The Child Status Protection Act (CSPA) was created to prevent exactly that. Use our calculator below to see whether your child's CSPA age keeps them protected, and read on to understand how the law actually works.

    What Is the Child Status Protection Act (CSPA)?

    The CSPA is a federal law that protects certain children from losing their eligibility for a green card simply because USCIS took too long to process their family's case. Under normal immigration rules, a "child" must be unmarried and under 21. Because family and employment-based green card cases can take years — sometimes over a decade — many children turned 21 before their case was ever decided, losing their place in line through no fault of their own.

    The CSPA addresses this by allowing part of the time a petition spent waiting for approval to be subtracted from the child's actual age. The result is the child's "CSPA age" — and if that number is under 21, the child generally keeps their eligibility to immigrate as a child, even if they're older than 21 on the calendar.

    What Happens If Your Child Doesn't Qualify?

    A CSPA age of 21 or older isn't necessarily the end of your family's case. Depending on the circumstances, there may still be options — such as converting to a different visa category, filing a new petition, or pursuing other forms of relief. Every case is different, and the right next step depends on the details of your petition, your category, and your family's specific situation.

    This is exactly the kind of decision that benefits from an experienced eye. A calculator can tell you where the numbers land — it can't tell you what to do next.
