What must be verified to ensure an alien's admissibility?

To determine an alien's admissibility, it is essential to verify the purpose stated in their visa and any grounds for inadmissibility. This verification helps ensure that the individual is entering the country for the reasons specified in their visa and that they do not fall under any categories that would make them inadmissible. The purpose of the visa may relate to tourism, work, study, or other activities, and confirming that the alien intends to honor those conditions is crucial for maintaining immigration integrity.

While personal history, length of stay, and travel companions may play a role in broader immigration considerations or in assessing risk, the primary focus for admissibility hinges on the visa’s purpose and any associated inadmissibility issues, which directly impact whether an alien can enter or remain in the country legally.
