Applicants refused a visa will always receive a letter at the interview explaining the reason for the refusal.  Applicants are welcome to reapply for a visa when there is a significant change in their personal circumstances.   

NOTE: The Visa Information Service can only provide information on nonimmigrant visas, application procedures, as well as schedule nonimmigrant visa appointments if one is required. A specific explanation regarding why your visa application may have been refused is not available from this service.
