Iternational sessions

Client in Ireland. Doxy used there or other European countries?

I am not a computer techie, but my understanding it that the internet knows no international boundaries unlike the telephone. You, of course, would need to address issues around licensure/temporary licensure in a foreign country, liability coverage and emergency back up plans overseas, but in terms of the internet including Doxy works just like it does connecting to someone in the US.
My experience is that each country is very different in what they allow in terms of overseas therapists seeing individuals residing in/visiting their countries. An interesting exception I read about is that it is acceptable to see someone if they are located within a US Embassy even if you aren’t licensed in the country where the embassy is located (which state’s licensure laws would apply?). I hope this helps.
