I just have to echo all of the wonderful points made in this thread about how this sort of situation rarely ends well for the client. Even for a professional consultation. Even if it were just "one time." The complications are many.

Professionals are in a unique position within mental health and have a duty to keeping clear and delineated boundaries because of the work they do. I already have some concerns about a mental health professional who is hosting social events for people who come to him for mental health advice and support. It seems harmless enough, but it's not the same as a bunch of folks coming together to discuss baseball from a baseball forum, now is it?

There are many excellent specialists who can offer second opinions. Any additional insight this particular doc may have into your situation is readily going to be offset by the creation of a dual relationship -- interacting with him as a forum member, and then interacting with him as a client. Dual relationship is then established, which, ethically, he is obligated to avoid when possible. And in this case, it would be easily possible.

So yes, come to the U.S. for a second opinion, but choose from one of the many other fine doctors in the same area that he practices, as you're not really limited by lack of choices there.

My two cents, take it for what it's worth...
