First of all I changed the title. As I mentioned It wasn't my intention to blame the support, I like you all.
Thank you, a link would be good for me, because there is a legit 2010 convention between our countries.
(there is a newer, but that's not yet been ratified by U.S. Gov.)
My problem was that the link in "Tax Infromation" menu, is pointing to an outdated convention. (Hungary 1979)
I belive that we can work as partners in the future, that's why I indicated this problem.
Question
Can I attach the updated convention documents with the new interview?
