Scope and purpose
The opinion interprets the statutory trigger in 8 U.S.C. §1229b(d)(1). It concerns the continuous-presence calculation for cancellation, not a universal rule that an immigration court has no authority whenever a notice omits a hearing date.
Related rules and practical context
Niz-Chavez later addressed the single-document requirement for this trigger. Read Form I-862 and subsequent notices against the record, INA §240A and later authority; neither decision by itself proves every cancellation requirement.
