Consulate Regulations:

Some consulates have their own regulations or are stricter in obeying Russian visa rules. If you want to be on the safe side contact your nearest embassy/consulate. Here are the main consulate rules:

Visa processing starts only after you have delivered all necessary documents. All paperwork once submitted is not subject to any change.
The fee for visa processing is not refundable. In case the applicant requests correction of the visa due to various reasons (except mistakes of the consulate staff) the applicant will have to re-apply for a new visa.
The consulates have different processing periods. Normally the slowest though cheapest period lasts about 3 weeks whereas the fastest way would cost you more than 100 Euro.
Tourist visas must be issued al least 2 days prior to departure stated on the invitation.
the visa will be issued exactly as indicated on the invitation. You can travel to Russia within the visa period.
Please note, that Russian consulates are closed during Russian holidays (sometimes also the day after) and on holidays of the host country.
