审核关系真实性时看两件事：类别是否齐全，以及时间上有没有断档。
第二件最容易被忽略。一堆婚礼照片加上最近三个月的聊天记录、中间两年空着——这恰恰是最常被追问的形状。 把材料一行一条列进来（日期精确到月就够），代码按季度画出覆盖时间轴，找出最长的那段空白，同时按八类比对：共同居住、共同财务、共同旅行、沟通记录、亲友与社会关系、官方文件、照片、共同生活痕迹。
空档不一定要找新东西——多数人手上其实有，只是没想到算材料：那段时间的聊天记录、转账、机票、寄到同一地址的快递、甚至外卖订单。如果那段时间确实分开（跨国关系里很正常），就用沟通记录填满它并主动说明原因——主动解释的空档不是问题，无法解释的才是。
还有两项补起来最快、也最常被忽略：把对方列为保险受益人或紧急联系人，以及同一地址的第三方文件。这两样都是当天就能做的。
整理方式同样影响结果：按类别分册、每册按时间排；聊天记录抽样不要全量（几百页的效果通常是负的）；照片按时间分散，一次婚礼五十张不如五年里每年几张；证明信写具体事例——「我参加了他们某年某月的婚礼」远胜过「他们感情很好」。
各国各类别的具体要求这里一个都不给（写错了会让你按错误的清单准备几个月），只给该去读哪份原文。$3 解锁按缺口的补材料路径、证明信模板与抽样方法、以及面谈可能被追问的方向。
Assessors look at two things: whether the categories are covered, and whether there are gaps in time.
The second gets overlooked. A pile of wedding photos plus three months of recent chats, with two years empty in between, is exactly the shape that invites questions. List your evidence one item per line (month precision is enough) and the code plots quarterly coverage, finds the longest empty stretch, and checks eight categories: cohabitation, shared finances, travel together, communications, family and social ties, official documents, photographs, and traces of shared daily life.
A gap rarely needs new material — most people already have something and didn't think it counted: chats from that period, transfers, flights, parcels to the same address, even food delivery orders. If you genuinely were apart (normal in a cross-border relationship), fill it with communications and explain the reason yourself — an explained gap isn't a problem; an unexplained one is.
Two items are the fastest to add and the most often missing: naming each other as insurance beneficiary or emergency contact, and third-party documents to a shared address. Both can be done today.
Presentation matters too: organise by category, each in date order; sample the chat logs rather than printing everything (hundreds of pages usually hurts); spread photographs across time — fifty from one wedding is worth less than a few per year; and letters of support should describe specific incidents, not general praise.
No country's requirements are stated here — following a wrong checklist wastes months — only which primary source to read. $3 unlocks routes to fill each gap, letter templates and sampling method, and the directions an interview tends to probe.

本工具不提供法律或移民建议，不代表任何国家的审核标准，也不预测任何申请结果。 各国、各签证类别对关系证明的要求、形式、认证与翻译规则、面谈方式与时限差异极大且经常调整，本工具刻意不提供任何具体规定——请以你申请的那个国家该类别的官方指引原文为准，或咨询持牌移民律师／有资质的顾问。八类分类与时间轴是本工具的整理口径，不是任何机关的评估框架。所有材料必须真实。 伪造材料、安排虚假关系或提交不实陈述在几乎所有国家都构成严重违法，后果远超一次拒签，通常影响此后所有申请并可能涉及刑事责任。请勿在此填写护照号、身份证号或住址。你填写的内容不入库。
This is not legal or immigration advice, represents no country's standards, and predicts no outcome. Requirements for relationship evidence — the categories, formats, certification and translation rules, interviews and time limits — vary enormously by country and category and change often, and none are stated here; rely on the official guidance for the specific country and category, or a licensed immigration lawyer or accredited adviser. The eight categories and the timeline are this tool's own organisation, not any authority's framework. Everything submitted must be genuine. Fabricating evidence or arranging a sham relationship is a serious offence in virtually every jurisdiction, with consequences far beyond a refusal — typically affecting all future applications and potentially criminal. Do not enter passport or ID numbers or addresses. Nothing you enter is stored.
