You can use any one event below

customer_save_before, customer_save_after

<global>
    <events>
        <customer_save_after>
            <observers>
                <change_customer_group>
                    <type>singleton</type>
                    <class>modulename/observer</class>
                    <method>ChangeCustomerGroup</method>
                </change_customer_group>
            </observers>
        </customer_save_after>
    </events>
</global>
