If your I-130 petition (Petition for Alien Relative) is denied, it means USCIS has decided that you did not meet the requirements to prove a qualifying family relationship or eligibility under U.S. immigration law. Common reasons for denial include insufficient evidence of the relationship, failure to meet eligibility requirements, mistakes in the application, or suspicion of fraud. When a petition is denied, USCIS will send you a written notice explaining the reasons. Depending on the case, you may be able to file an appeal with the Board of Immigration Appeals (BIA), submit a motion to reopen or reconsider with USCIS if new evidence is available, or re-file a new I-130 with stronger documentation. In some situations, working with an immigration attorney can help determine the best next step.
