I am student in Russia from Pakistan I am planning to go in Schengen states for tourism for 2 weeks on holidays. Can I apply for that tourist visa ?
You can apply. The application will go to the embassy or consulate belonging to the main destination of your trip which is responsible for your place of residence. As a student in Russia, you are probably a resident of some town in Russia. If that is not the case, you are a resident some town in Pakistan.
Your application may be denied. The Schengen area tries to admit all genuine tourists and to exclude all illegal immigrants. Part of the decision is based on your ties to your home country and to your place of residence. As a resident in Russia, your ties to Pakistan are probably weak. As a citizen of Pakistan, your ties to Russia are probably weak.
Your application may be granted. If the rest of your application is strong, that can overcome weak ties to your place of residence.
