Applicants are usually required to be present in the visa office. If you cannot come in person, you may entrust a relative, friend, or travel/visa agent to come and submit the application on your behalf. No appointment is necessary for visa applications. The Consulate does not accept visa applications by mail.

It normally takes 4 working days to process the visa application.
