A marriage-based green card case seems simple at first because the relationship itself feels obvious to the couple involved, but USCIS does not personally know them, so the application has to show that the marriage is genuine through evidence. That is where many people who are researching how to apply for green card https://consultantlm.com/services/applying-for-a-green-card status through marriage realize that the paperwork is really about documenting a shared life, not just submitting a marriage certificate. Joint financial records can be useful because they show that the couple has combined at least part of their day-to-day responsibilities. Bank statements, jointly filed taxes, shared credit accounts, leases, mortgages, or utility bills can all help. Insurance policies are another strong example, especially when spouses name each other as beneficiaries or are covered under the same health, auto, or renters policy. Shared residence is also important, although it does not always look the same for every couple. Some spouses live together from the beginning, while others spend periods apart because of work, study, military service, immigration delays, or family obligations. In those situations, travel records, messages, call histories, visits, shipping receipts, and other documents can help explain how the relationship continued despite the distance. Photographs are useful too, but I would not rely on hundreds of selfies. A smaller number showing the couple at different stages of the relationship, with relatives, at holidays, trips, or important events probably tells a clearer story. Correspondence between spouses can add context as well, especially when it covers a meaningful period rather than looking like something created only for the application. Testimony also matters. During an interview, officers may ask about how the couple met, where they live, important family events, finances, routines, and future plans. The goal is not necessarily for both people to remember every minor detail identically, but major inconsistencies can create questions. I think the harder cases are couples who do not have much traditional joint documentation. Maybe one spouse moved in recently and is not yet on the lease, one person handles most finances, or cultural circumstances kept accounts separate. That does not automatically mean the relationship is weak. Alternative evidence could include affidavits from people who know the couple, records of regular travel, shared subscriptions, emergency contacts, beneficiary designations, correspondence with landlords, joint purchases, or documentation showing plans made together.
