Can I open an account directly with IBKR after closing my Introducing Broker account?

Delinking from an Introducing Broker is not supported. Please contact your Introducing Broker for any questions regarding closing your account. 

Some Introducing Brokers require a 6 month cool-down period before you can open an account directly with IBKR. Please check directly with your Introducing Broker to determine if there are any restrictions.
