已接入美国国务院官方数据
VisaDataHub now uses U.S. Department of State public releases:
- Adjusted B Visa Refusal Rate by Nationality (fiscal-year PDFs)
- Global Visa Wait Times (latest published estimated appointment waits)
Refusal rates are not an individual’s probability of refusal or approval. Wait times distinguish Average Wait Time from Next Available Appointment and are not real-time.
Each module links back to the official source and shows last official update / last checked timestamps.
