A Schengen visa is required for citizens of certain countries who wish to enter any of the Schengen Area countries for a temporary stay, including for language courses. The Schengen Area is comprised of 26 European countries, including popular language learning spots such as Germany.

Language courses are considered a non-qualified post-secondary education program and are included in the Schengen visa requirements as a 'short-stay stay for purposes of study'.

The requirements for a Schengen visa for language courses include:

• Applying through the consulate or ویزای مولتی شینگن embassy of the country you plan to spend the most time in, or in some cases, the country where you are a domicile.
  
• Ensuring your passport is valid for a minimum of five months after you plan to depart from the Schengen Area.
  
• Having a minimum of three blank pages in your passport for the visa.
  
• Submitting specific documentation, including, but not limited to:
  

- Filled out and submitted visa application form
- Standard photo (biometric data may also be collected)
- Proof of payment for the language course course expenses
- Proof of health insurance that covers you for the duration of your stay in the Schengen Area
- Proof of financial resources, such as a bank statement indicating required funds to support yourself during your stay
- Proof of your accommodation in the Schengen Area

• Meeting the language course requirements, including:
  

- Taking an entry-level language course of at least 280 teaching hours or 14 weeks duration
- Receiving a confirmation of registration or an official letter from the institution offering the language course

It is vital to note that you should NOT start your language course before you have received a answer on your visa application, as this may result in your visa being rejected. Furthermore, do not use your visa to extend your stay in the Schengen Area, as this might also result in your visa being withdrawn.

Furthermore, keep in mind that visa applications take time to review, and it is recommended to submit them at least 4-8 months before the start of the language course, in order to ensure that your application meets the visa requirements and you are allowed to enter the Schengen Area without any issues. Additionally, check the specific requirements for your country as requirements may change and not all countries are entitled to Schengen visa free travel.
