Dennis did get his O-1 (exceptional athlete) visa from the USA, and he is in the process of attempting to have his five year ban reversed (it's a cumbersome process now going through the US Embassy in Manila). He did attempt to get a visa to go to the UK but did not receive it in time. In fact he is still waiting to hear back from the UK Embassy in Manila. The wheels of justice move slowly it appears. This entire legal process has been one long expensive slog.
Well the only way to make wheels of Justice is move fast in this case is Congressional Inquiry.
Have friend working for Member of Congress, or make large political contribution to get help maybe.
Thanks for up date Jay.
