may I know the requirement for visa application and how long does it take to be out?

Hey, you can apply for it through agencies or in person. If you want to apply in person, you should first make an appointment online and then go to the embassy or consulate to submit the application and have an interview. You may need to provide the following materials: a filled-out application form with your signature on it, a passport and a photocopy of the passport’s photo page, two same recent passport type photos against white background, and the original and photocopy of a medical insurance covering all Schengen countries and the whole stay.

The processing takes three working days.
