The marriage is genuine. The relationship is real. The couple has been together for years, built a life together, and done everything right in their personal lives. And yet the green card case falls apart. This happens more often than most people realize, and in the overwhelming majority of cases, it is not because USCIS found evidence of fraud. It is because of avoidable, procedural mistakes that could have been caught and corrected with the right preparation and guidance.
Here are the four most common reasons real marriage green card cases fail, and what you can do to make sure none of them happen to yours.
Mistake One: A Weak Affidavit of Support With No Joint Sponsor
The Affidavit of Support, filed on Form I-864, is one of the most consequential documents in a marriage green card case. It is the legal commitment by the U.S. petitioner to financially support the immigrant spouse, ensuring they will not become dependent on government assistance. USCIS and the National Visa Center take this document seriously, and cases that have an insufficient Affidavit of Support come to a hard stop.
The most common version of this mistake is a petitioner whose income falls below the required threshold for their household size. The federal poverty guidelines set a minimum income requirement, and if the petitioner does not meet it, the case cannot move forward without either addressing the income shortfall or bringing in a joint sponsor, a third party who agrees to share the financial responsibility.
What makes this mistake so damaging is that it is entirely predictable. The income requirements are published, the calculation is straightforward, and the solution, whether that means a joint sponsor or additional financial documentation, can be arranged in advance. Cases stall at this stage not because the problem is unsolvable but because couples did not address it before filing or before reaching the NVC stage. Do not wait until the NVC asks for the Affidavit of Support to figure out whether you qualify. Know your numbers before you start.
Mistake Two: Submitting Nothing More Than a Marriage Certificate
A marriage certificate proves that a legal marriage took place. It does not prove that the marriage is genuine. These are two very different things, and USCIS evaluates both.
When the only evidence submitted to support the bona fides of a marriage is the certificate itself, the case is immediately vulnerable. Officers are looking for a rich, documentary picture of a real relationship built over time. That means photographs of the couple together across multiple years and occasions. It means communication records showing ongoing contact, messages, calls, and correspondence over the course of the relationship. It means joint financial documents such as shared bank accounts, joint tax returns, or evidence of shared expenses. It means proof of shared residence. It means affidavits from people who know the couple and can speak to the authenticity of their relationship.
The evidence package is not a formality. It is the core of the case. A thin evidence package on a genuine marriage can look indistinguishable from a fraudulent one to an officer reviewing a file. Build your evidence deliberately, comprehensively, and well before you need to submit it.
Mistake Three: Inconsistencies Between Current Forms and Past Immigration Documents
This is the mistake that can turn a straightforward case into a serious legal problem. Every immigration application you have ever filed is part of your record. When you submit new forms as part of a marriage green card case, USCIS compares the information you provide against everything you have previously submitted.
Address history, employment history, travel history, and personal background details must be consistent across all documents. If your current application lists a different employer for a period where a past visa application showed something different, that inconsistency raises a red flag. If your address history does not match what was submitted on a prior tourist visa application, that discrepancy will be noticed. If dates do not align, if names are spelled differently, if any information contradicts something previously submitted to the government, it can lead to a finding of misrepresentation.
Misrepresentation is one of the most serious grounds for denial in immigration law. In some cases it can result in a bar from entering the United States. The solution is not to hide information. It is to review your entire immigration history carefully before filing, identify any discrepancies, and address them honestly and proactively in your application. An experienced immigration attorney will do this review as a standard part of case preparation. It is not optional.
Mistake Four: Missing the I-751 Deadline After Receiving a Two-Year Conditional Green Card
This final mistake is heartbreaking because it happens after the hard work is done. A couple goes through the entire green card process, gets approved, and receives a two-year conditional green card. Then life gets busy, the deadline gets overlooked, and the conditional green card expires without the I-751 removal of conditions petition being filed.
The consequences are severe. USCIS can terminate permanent resident status for failure to file on time. The case can be referred to an immigration court for removal proceedings. A couple that successfully obtained a green card through a genuine marriage can find themselves facing deportation not because of anything fraudulent but because they missed a filing deadline.
The I-751 must be filed within the 90-day window before the conditional green card expires. Mark that date on your calendar the moment you receive the card. Set multiple reminders. Work with an immigration attorney well in advance of that window to prepare the petition properly.
The pattern across all four of these mistakes is the same.
Every one of them is avoidable. Proper financial preparation eliminates the Affidavit of Support problem. Thorough evidence gathering eliminates the thin file problem. Careful review of immigration history eliminates the inconsistency problem. And a calendar reminder eliminates the missed deadline problem. None of these require extraordinary effort. They require attention, preparation, and the right guidance from the start.
