Name two reasons a visa may be denied.

A visa may be denied for a variety of reasons, two of which include insufficient documentation and grounds of inadmissibility. Insufficient documentation refers to failing to provide all necessary paperwork to support a visa application, such as proof of identity, relationship to a U.S. citizen or resident, or evidence of ties to the home country. Without this documentation, consular officers may not have enough information to assess an applicant's eligibility.

Grounds of inadmissibility are specific legal reasons that disqualify a person from entering the U.S. These can include criminal activities, previous immigration violations, or certain health-related issues. If an individual has a history that falls under these grounds, their visa application is likely to be denied regardless of other factors.

The combination of these two reasons highlights the importance of thorough preparation and understanding of the U.S. immigration laws and requirements when applying for a visa.
