USCIS Updates Policy on DNA Evidence in Support of Sibling Relationships
On April 17, 2018, USCIS updated its policy on the acceptance of DNA evidence supporting sibling relationships. The policy permits officers to suggest and consider direct sibling-to-sibling DNA test results, and provides standards for evaluating DNA results for full siblings and half siblings.
When USCIS determines that primary evidence is unavailable or unreliable, it may suggest and accept DNA test results as evidence of a full-sibling or half-sibling relationship in any petition or application for an immigration benefit in which a sibling relationship is required to establish eligibility or may otherwise be relevant to an eligibility determination.
USCIS does not currently have regulatory authority to require DNA testing. This new policy may only suggest DNA testing as an option for proof of a familial relationship.
