The law provides for both. The conditions are set by presidential decisions that are not in this act.
The Investment Law provides for two immigration routes tied to investing. Foreign investors who are founders or participants of enterprises with foreign investments have the right to obtain an "investment visa", and their spouse, parents and children a guest visa for its duration, extendable without leaving Uzbekistan; foreign investors who have invested in organising enterprises that produce goods or supply services are issued a residence permit in a simplified procedure. Holders of either, and their families, may work in Uzbekistan and use medical and educational services on the same footing as citizens, including secondary and higher education.

What the law does not supply is how. Both are granted "on the conditions established by decisions of the President", and the procedure for issuing them is established by the Cabinet of Ministers — acts that are not part of this law. Note also whose visa it is: the investment visa is written for founders and participants of an enterprise with foreign investments, which is a defined status with a capital and production test, not simply any foreign-owned company.
