The condition and requirement of converting to Islam is to testify that there is one God, the Almighty God, and Prophet Muhammad (s.a.w.) is the Messenger of God.
This is the shahadah, or shahadatayn, or what some refer to as the "kalimah".
As for testifying to the Wilayah of Imam Ali (a.s.), this is not an essential componant of converting to Islam. Once one is a Muslim, they will choose the type of Islam they will be affiliated to. Of course, our belief is the only true Islam is the Islam represented in the Progeny of Prophet Muhammad (s.a.w.), the Ahlul Bayt (a.s.) - the Twelve Imams (a.s.).
And Allah knows best
