You can check the status of your visa application on ceac.state.gov.
Some visa applications require further administrative processing, which takes additional time after the visa applicant’s interview by a consular officer. Applicants are advised of this requirement when they apply. When administrative processing is required, the timing will vary based on the individual circumstances of each case.
If your visa application was refused with a “214 (b)” notation, it is a final refusal for this application. Section 214(b)* denials are not permanent. If you have new information or if your overall circumstances have changed significantly, you may reapply. Applicants who provide identical information in a second interview rarely get a different result.
If your visa has been denied, you may find useful information on Ineligibilities and Waivers on usvisas.state.gov.
