在境内维持身份的人，同时跑着好几个互不相干的倒计时：证件到期、身份到期、宽限期结束、材料处理周期、失业天数累计。它们的起算点各不相同，所以在日历上排不到一起——而任何一个超一天，后果都不是「晚一点」，是掉身份。 工具做的就是把它们排到同一条时间轴上，标出最近的那条红线，并给每个节点两次提醒的建议（到期前 60 天准备材料，30 天确认已递出）。 有一件事必须说清楚：**所有天数都由你自己填，工具不提供任何国家的期限数字**。宽限期多长、失业上限是多少、递交后身份是否自动延续——这些逐国、逐身份类别、逐年不同且改动频繁，而报错一个数字的代价不是重填表，是失去身份或影响未来多年的申请资格。 还单列了三个致命误解，其中最常见的是「递交了申请就安全了」——递交与获批是两回事，递交后是否自动延续取决于你的类别，必须确认，不能假设。$2/月订阅解锁多身份并行排期、每个节点前的动作清单、以及材料递交后的跟进节奏。Anyone maintaining status abroad is running several unrelated clocks at once: document expiry, status expiry, the end of a grace period, processing time, accumulated unemployment days. They start from different dates, which is exactly why they can't be held in one calendar — and being one day over on any of them isn't "a bit late", it's a loss of status. This puts them on one timeline, marks the nearest red line, and suggests two reminders per item — sixty days out to prepare, thirty to confirm it was filed. One thing must be clear: **every duration is your input; the tool supplies no country's periods**. How long a grace period runs, what the unemployment cap is, whether filing extends status — these differ by country, by status category and by year, and change often. Getting one wrong here doesn't mean refilling a form; it means losing status or affecting eligibility for years. Three fatal misconceptions are called out, the commonest being "I filed, so I'm fine" — filing and approval are different things, and whether filing extends status depends on your category and must be confirmed rather than assumed. $2/month unlocks multi-person scheduling, per-milestone action lists, and follow-up cadence after filing.
每个节点前 90/60/30 天的动作清单（该准备什么、找谁、要多久）+ 多个人并行排期（配偶与子女的身份往往跟着主申请人但期限不同）+ 材料递交后的跟进节奏与该在什么时候开始担心 + 出行前的检查清单（离境再入境是身份中断的高发点）。Action lists at 90/60/30 days before each milestone, scheduling for a whole family whose statuses derive from one another but expire differently, follow-up cadence after filing and when a delay becomes worth chasing, and a pre-travel checklist since re-entry is where status most often breaks.
本工具只做日期排列与算术，**不提供任何国家的移民规定、期限或宽限期天数**，也不是法律或移民意见。所有天数与期限由你自行填写，请从所在国移民主管部门的官方来源、你手上的文件、或学校国际学生办公室与雇主的移民支持团队核实——论坛与经验分享不是来源。处理周期为估算，实际波动很大，不能作为任何决定的依据。递交材料后身份是否自动延续、宽限期是否适用、失业天数如何计算，均取决于你的具体身份类别与现行规定。如果你已经超期、接近超期、或不确定自己的处境，请立即咨询有资质的移民律师——这件事上自行判断的代价过高。你填写的内容不入库。This performs date arithmetic only. It **states no country's immigration rules, periods or grace-period lengths** and is not legal or immigration advice. Every duration is your input; verify it against your country's immigration authority, your own documents, or your institution's international office or employer's immigration team — forums and shared experience are not sources. Processing times are estimates that vary widely and must not be relied on for decisions. Whether filing extends status, whether a grace period applies, and how unemployment days are counted all depend on your specific category and the rules in force. If you are past a deadline, near one, or unsure of your position, consult a qualified immigration lawyer immediately — self-assessment here is too costly. Nothing you enter is stored.
