Xiaoyi Guo is delinquent on the New York attorney register file of Sep 29, 2026. Admitted in 2018 in the First Department, with an office in Dallas, TX; next registration due Dec 2026. The status is the same in all 3 files we hold. The month shown is the next cycle’s; the delinquency concerns an earlier registration the register did not receive.
What this status means on the register
On the register, “Delinquent” means the attorney has a registration the register shows as due and not received. Under the rule a failure to register results in referral to the Appellate Division for disciplinary action; the register does not show whether a given attorney was referred.

How to confirm it officially
For a statement of Xiaoyi Guo’s standing, contact the Attorney Registration Unit of the NY Office of Court Administration (nycourts.gov/attorneys), or ask the Appellate Division, First Department, which admitted Xiaoyi Guo in 2018. The register places the office outside New York, so a complaint would go to that department’s grievance committee (22 NYCRR 1240.7(a)(2)).
This page reads the register file of Sep 29, 2026, and the court system’s own search can be newer; the register shows only the current value, so a suspension that ended before the files we hold, or a censure, leaves no trace here (Appellate Division decisions are published through the court system’s Law Reporting Bureau).
