What are common grounds of inadmissibility to the United States, and how can an applicant address these issues when applying for a visa or green card?

Common grounds of inadmissibility include prior immigration violations, criminal convictions, health-related issues, misrepresentation, or security concerns. Applicants who fall under any of these categories may be denied entry or green card eligibility unless they obtain a waiver of inadmissibility. Waivers often require proving extreme hardship to qualifying U.S. relatives, evidence of rehabilitation, or other mitigating circumstances. Proper legal guidance is crucial when addressing complex inadmissibility issues to improve the chances of approval.
