Set Up Your Visa Interview
If you are not eligible to travel under the Visa Waiver Program, you may be required to appear at a U.S. embassy or consulate for an in-person interview prior to visa approval. There may be long waits to schedule an interview, so start the application process as early as possible.

Visa Wait Times
The U.S. Department of State's Bureau of Consular Affairs provides visa wait times for every U.S. Consulate worldwide.
Some applications require additional "administrative processing" and this adds several weeks to the application process. Applicants involved in scientific fields are often subjected to administrative processing and should apply for visas as early as possible, preferably 3-4 months in advance. Bring your CV and letter of invitation to the visa interview to help facilitate any additional processing.
