When facing denials of visas or green cards, it's essential to be aware of your legal options. Common reasons for denials include ineligibility, incomplete or incorrect documentation, and requests for evidence (RFEs). To address these denials, you can reapply with the correct documents, respond to RFEs, or request an administrative review. In some cases, you may appeal or file a motion to reopen/reconsider. Consult an immigration attorney for guidance. Additionally, consider waivers for inadmissibility issues, and be cautious not to repeat mistakes when reapplying. Each case is unique, so understanding your specific situation is crucial for a successful outcome.
