My wife and I are planning on travelling long term abroad beginning in the Fall of 2004 or Spring of 2005. We would probably be staying several months at a time in different countries and would also be looking at moving to one of them on a permant basis. We are looking primarily at Europe and Australia.

I know that visa regulations and other applicable laws differ, but am looking for general information on my situation and have had a lot of difficulty finding any.

My wife works for a counselling and entertainment telephone service in the US, where we reside and are citizens. With the advent of VoIP it is practicle for her to continue with her independant contract work (ie she is self employed) anywhere abroad that we could have high-speed internet. I am beginning to work doing internet marketing and entertainment and again I could do this from anywhere in the world with good internet access. Neither of us recieve any income from a business in a nation we would be visiting.

Would we (generally) need work permits and visas to continue this on our travels abroad? Could we just do this on tourist visas? Given our situation and the specific nature of our business I think obtaining a work permit and visa would be very difficult for us.

Thank you in advance for any help or direction you might be able to offer.
