  "root_cause": "Under the US Visa Waiver Program (VWP), a traveler who exits the US to Canada or Mexico and re-enters by land does NOT get a new 90-day stay. Instead, they are admitted for the remainder of their original 90-day period (or up to 90 days if they have not yet used any time). This is because VWP rules treat contiguous territory travel differently from overseas travel. Only a flight from outside the US (e.g., from Europe) resets the clock. Many travelers mistakenly believe a quick land border crossing resets their stay.",

  "root_cause_zh": "根据美国免签证计划（VWP），离开美国前往加拿大或墨西哥并通过陆路重新入境的旅客不会获得新的 90 天停留期。相反，他们被允许停留原 90 天期限的剩余时间（如果尚未使用任何时间，则最多 90 天）。这是因为 VWP 规则将毗邻领土旅行与海外旅行区别对待。只有从美国境外（例如欧洲）乘飞机入境才能重置计时器。许多旅客错误地认为快速陆路边境穿越可以重置停留时间。",
