Hi Senior,
welcome to the forum, nice to read that you, may I say as a mature student, want to do the PhD.
There are various international MBA programmes in the EU, taught in English, and I presume they may offer a PhD (or more likely a DBA) as well. You probably know these better than I do, schools like ESADE, IE, INSEAD, Erasmus etc. come to mind.
I do not know how this would work regarding residency, I think it depends on your nationality. If you are from the EU you can just start in any country in the EU, if not from the EU I think you probably need to contact the embassy of the country you want to go to and ask about visa etc.
