Since August 5, 2026, USCIS officers must mention DNA testing whenever they ask for more evidence of a parent-child or other genetic relationship. DNA stays optional, you pay for it, and saying no cannot be the only reason for a denial. What changed and how to respond.
On August 5, 2026, USCIS issued Policy Alert PA-2026-06. It changes five chapters of the USCIS Policy Manual. The main change is in Volume 1, Part E, Chapter 6 (Evidence), under a new heading, “Optional Submission of DNA Testing.”
The new rule: when the evidence of a claimed genetic relationship is missing, unreliable or not enough, and the officer decides to ask for more evidence, the officer must tell you that you may submit DNA test results. Before, officers could suggest DNA only after both primary and secondary evidence had failed, and each USCIS directorate had its own practice.
DNA testing stays voluntary. The Policy Manual says USCIS has no statutory or regulatory authority to require it. If you choose to test, you pay all the costs. USCIS will tell you where to find a list of laboratories accredited by AABB.
If you do not send DNA results, USCIS will not send a second request just to suggest DNA again. It decides the case on the record. Not sending DNA should not be the only reason for a Notice of Intent to Deny (NOID) or a denial, but a case can still be denied if the relationship is not shown by a preponderance of the evidence.
The guidance took effect immediately and applies to cases pending on August 5, 2026 and to cases filed after that date. USCIS says it also aligns with section 9 of Executive Order 14165, which tells DHS to use available technologies to check claimed family relationships.
Some USCIS cases depend on proving that two people are related by blood, for example a parent and child. The usual proof is a birth certificate that was registered on time by a government office.
Sometimes there is no birth certificate, it cannot be obtained, or USCIS does not trust it. For example, the State Department may report that records from a country are unreliable, or the certificate may have been registered years after the birth. Then you must send other evidence, such as school or church records or sworn statements.
If USCIS still is not convinced and sends you a request for more evidence, the request must now also tell you that DNA test results are an option. This lets you send everything at once, instead of waiting for a second request.
You do not have to take a DNA test. If you choose to, you pay for it, and the test should be done through an AABB-accredited laboratory. If you decide not to, USCIS will look at whatever else you sent and decide the case.
