Expert Answer: Waiting times for visa-based entries can often be longer compared to other immigration processes. This is due to factors like annual numerical limits, high demand for certain visa categories, and the varying processing speeds at different U.S. embassies or consulates. Your specific visa type, country of origin, and the current workload at the consulate all influence how long you might wait for an interview. For the most accurate information, check the website of the relevant embassy or consulate, and consider consulting an immigration attorney for personalized advice.
