Choose company name

Words like "Russia/Russian" or even 'Rus'+some other letters or words may not be freely used in the name of the company. They are subject to specific statutory approval. You may be rejected company registration on this (among other multiple reasons) ground. You need to obtain a specific statutory approval and pay a fee in order to use it. General recommendation is to avoid such words in your company name altogether. Words or abbreviations, which may be regarded as misleading shouldn't be used to avoid rejection of business registration.
