The Second Circuit deferred to the Board of Immigration Appeals' (BIA) decision in Matter of Camarillo and determined that proper service of a Notice to Appear (NTA), even if it does not specify the time and date of a court hearing, is sufficient to stop the accumulation of physical presence necessary for a cancellation of removal application. In doing so, the Court reiterated some of the reasons relied on by the BIA for finding that service of the "incomplete" NTA was sufficient to trigger the stop-time rule, including that scheduling of hearings is handled by the Department of Justice, while service of the NTA is handled by the Department of Homeland Security and the stop-time rule was enacted to ensure that non-citizens did not have a motivation (i.e. the continued accumulation of physical presence) to prolong their proceedings unnecessarily.
