You, as a visa applicant, qualify for a visa by being eligible under all applicable U.S. laws for the visa category for which you are applying. During your visa interview, the consular officer at the U.S Embassy or Consulate will determine if you are qualified for the type of visa for which you are applying.
The sole authority to approve or deny (called adjudicate) visa applications, under U.S. immigration law section 104(a) of the Immigration and Nationality Act, is given to consular officers at U.S. Embassies and Consulates.
