In principle, arbitrarily far. The velocity decreases with the distance because the attractive gravitational acceleration has to match the centrifugal one, $$ \frac{GM_\text{Earth}}{R^2} = \frac{v^2}{R},\quad v = \sqrt{\frac{GM}{R}} $$ for a circular orbit. So the velocity decreases with the distance as a power law but it never gets zero.
