What is the CSPA age calculator?
The CSPA age calculator applies the common Child Status Protection Act formula: biological age when a visa becomes available minus petition pending time. Category rules and the seek-to-acquire requirement still matter.

- 2
Enter the first visa-availability date, determined from approval, Chart A, and the priority date.
- 3
The tool calculates biological age, petition pending days, and estimated CSPA age.

Frequently asked questions
What is the basic CSPA age formula?
The common formula is biological age when the visa becomes available minus the time the underlying petition was pending.
What is the seek-to-acquire requirement?
Many cases require action toward permanent residence within one year of visa availability, such as properly filing Form I-485 or Form DS-260. Exceptions are case-specific.
