After you receive your invitation letter via email, you can apply for the Russian visa at one of their embassies. You need to follow the next steps:

  1. Print your invitation in color.
  2. Submit the letter as well as all the other required docs for your visa application at the embassy. These typically include: color visa/passport-sized photo, health insurance, proof of finance, returns flights etc. (iVisa suggest that you consult directly with the embassy nearest to you for a full list of required documents).
  3. After your visa interview at the Russian embassy, they will issue you your visa if approved.
