One of the most popular posts on the iCouch blog was our 2015 article Crossing the line: a legal argument for interstate online therapy. Thousands of people have read it and it still enlivens debates on the topic of cross-state online therapy. I'm not going to rehash the main points here, please read the original! However, given that the most popular question we get at iCouch is "Can I practice online therapy across state lines?" we decided that another article was warranted!
