What did this case add to Pereira?
After Pereira v. Sessions, the government kept arguing that it could send the information in pieces. Mr. Niz-Chavez received the charges in one document and, two months later, the time and place in another. The Board had said the second paper perfected the first. The Supreme Court disagreed: the law speaks of a notice, so a notice that stops the clock is one document containing everything in 8 U.S.C. § 1229(a)(1). A later hearing notice cannot cure the first form. Many people who were served years ago hold exactly this pair of papers, which is why the ruling still matters. Next step: lay your Notice to Appear and any hearing notices side by side and see whether one sheet of paper alone carries the date, time and place.
What must that one document contain?
Section 1229(a)(1) lists the contents: the nature of the proceedings, the legal authority, the conduct alleged, the charges and the laws said to be violated, the right to a lawyer, your duty to give an address and report changes, the time and place of the hearing, and the consequences of missing it. The missing item in almost every dispute is the date and time. If a single form has them, this case does not help you, and your clock stopped on the day of service. Also read the Certificate of Service, which shows how and when you were served. Do not write on or alter originals. Next step: scan each page, including the back, and note the service date. Those two facts decide whether there is anything to argue.
Who can actually use this ruling?
Mainly people who would reach the required time only by counting past the date of a defective notice. That means 10 years of presence for non-green-card cancellation, or 7 years of continuous residence for green card holders. Abused spouses and children have a separate 3-year rule. Under Matter of Chen (2023), a final removal order does not stop the clock either. But the ruling does not reopen anything on its own. In Chen the motion was late, and the Board refused discretionary reopening because a change in law still requires showing you otherwise qualify. The Supreme Court's later Monsalvo Velázquez case records another instance: the Board held that Niz-Chavez did not justify reopening that man's case. Next step: if you have an order, read our page on motions to reopen before relying on this case, because the 90-day limit and the one-motion limit generally still apply.
What else can end or break my time?
Winning the notice argument does not protect the count from other events. The statute ends the period on the date you committed a covered offense, if that came before a proper notice. It does not matter that a form was defective. Trips are a separate problem: more than 90 days at once, or more than 180 days in total, breaks presence. The Board goes further. As Chen summarizes, shorter departures can also break presence if you left under a formal process that found you inadmissible or refused admission, or under threat of removal proceedings. A documented refusal at a port of entry may count. Next step: tell your lawyer about every arrest, even without a conviction, and every border encounter, with dates. Surprises here can end the application whatever your notice says.
Does the single-document rule apply to missed hearings?
No, and this is the costliest misunderstanding. People assume that because the first form was incomplete, an order for missing court must fall. The Supreme Court rejected that in Campos-Chaves v. Garland: a proper notice of the hearing you missed defeats rescission on this ground. The Board reinstated its matching Matter of Laparra rule in 2026 for any circuit without contrary precedent. Niz-Chavez still has force inside the case. The Board said in Matter of Aguilar Hernandez (2024) that DHS cannot fix the missing date by filing a Form I-261. Next step: treat every hearing notice as binding. If you missed a hearing, go straight to our in absentia guide, because a 180-day deadline may apply.
What should I do with this at my next hearing?
Use it for two separate purposes. First, if the form is defective and pleadings are still open, decide with a lawyer whether to object. The Board calls that a strategic decision in Matter of Aguilar Hernandez. The objection is yours to raise, not the judge's, and a late one is forfeited. But if you stay silent your time keeps counting, while if you object and DHS cures the notice, the clock stops. That matters most if you are close to 10 years. Second, if cancellation is your defense, tell the judge at the master calendar hearing and get a filing date for Form EOIR-42B. Cancellation still depends on hardship, moral character and discretion. To have your notice and your count checked before that hearing, start at our removal defense page. Next step: bring the notice, all hearing notices and your presence timeline.
