Ahsan, you should first prepare your passport, a photocopy of the passport's photo page, a completely filled-out application form affixed with your recent bare-headed color photo, the original and photocopy of your residence permit B, and other necessary documents required by the consular office. And then go to the office to submit your application. Generally speaking, the process takes four working days.
