I have applied for a TRV visa from LA consulate on July 3rd and I have not heard back from them yet (yes, they wouldnt respond to emails, fax etc). I have travel arrangements made to Canada on Aug 9th. How long is the processing taking? Should I walk into the consulate and find the status? Has anyone done this? I am a citizen of India and currently in USA on visitor visa. PLEASE let me know.
