Applying for a non-immigrant visa is not primarily a document-based process. The main issue in determining if an applicant qualifies for a visa is intent, and documents alone can not establish intentions. In some cases, documents can help establish an applicant’s intent to return to Argentina by showing that the applicant is well established here. In other cases, the circumstances are clear enough that documents are unnecessary. If your visa application has been refused it is highly unlikely that any document you could provide would alter the consular officer’s decision.
