Waiting for a family-based immigration case often brings hope, but it can also create new worries. One concern may arise when a child nears age 21 while the matter is still pending.
If you are petitioning for your son or daughter, you may wonder how that birthday could affect the result. Knowing the general rules can help you avoid delays and spot added requirements that may influence your family’s case.
Several outcomes are possible after a child turns 21
Turning 21 does not automatically end every immigration case. The result often depends on the visa category and whether the Child Status Protection Act (CSPA) applies. CSPA may protect a child’s immigration age. In most family-preference cases, USCIS subtracts the time the petition was pending from the applicant’s age when a visa becomes available.
To qualify, the applicant must remain unmarried when the visa category requires it. In some preference cases, the person must also seek permanent resident status within one year after a visa becomes available. Even with these rules, turning 21 may affect the petition in several ways. Possible results include:
- CSPA preserves eligibility. If the calculated age stays under 21 and the applicant meets the other rules, the person may avoid aging out.
- The petition moves to another category. Without CSPA protection, an unmarried son or daughter of a U.S. citizen may enter the Family First Preference category after turning 21.
- Protection no longer applies. If the calculated age is 21 or older, the applicant may age out and move to another family-preference category.
- The wait may become longer. A new visa category may have a larger backlog and delay permanent residence.
Since each result depends on the petition’s timeline and visa category, families should review the key dates closely.
Why filing dates matter
Small differences in filing dates, approval dates and visa availability can change the result. Those details often decide whether CSPA protection applies.
An attorney can examine the key dates and explain how the law may affect your family’s case. That review may also uncover a deadline or rule that needs prompt attention.
